CLC Pi Filter on SMPS for Tube Audio Circuit
Просмотров 1395 месяцев назад
In this video, I demonstrate how a CLC Pi filter can help minimize the switching noise in a SMPS output. In this case, the input is 24VDC and the output is -250VDC to -300VDC (adjustable). I try to compare the results with some frequency plots, but the spectrums are not entirely consistent as some measurements were loaded and others unloaded, which changes the temporal signal and frequency resp...

Mesa Boogie Express 5:25 Repair
Просмотров 5326 месяцев назад
In this video, I repair a mesa boogie express 5:25 amplifier. The infamous C36 tantalum capacitor in the regulated heater supply released the magic smoke and shorted out. I replaced the 7812 regulator IC, C50, C36, and then tested the amp with the proper wall voltage using a step-up transformer.

Cloudgazer - Tape playback 7.5IPS (half speed)
From sewing machine to maybe not being run the fuck over because they at least hear you 😂
The runt had a bad batch of capacitors. Friedman called the amps... i think they corrected it after 2019
Larger value resistors are quieter than lesser, look up shot noise, mechanical noise, the paint caused the body to not provide ground/faraday shielding, big waste of time though it worked out for u
not a waste of time at all, i learned quite a lot and you got a video out of it! it's a win win
Heard “Fool In the Rain”
A-21 win~
ROCK ON
KRK speaker was exhibiting buzz in both the tweeter and woofer. The circuit looked fine, but I replaced the PSU components hoping it would resolve the issue. It did not. The buzz was still there. I started probing the preamp to see where it was coming from but it seemingly appeared out of nowhere between two stages. Turns out the power transformer toroid rotated in shipping and the new orientation induced buzz/hum into the surrounding components. Easy fix but hard to find!
Wow I need lessons
Here's what my guitar amp sounds like! There's only five of these amplifiers in the world 🌎 each one built by me! They're single channel, 50 Watts, and all tube. Featuring four 12AX7 preamp tubes and two KT66 power amp tubes. What makes them unique (other than the looks!) is the positioning of the modifier switches in the circuit layout and how these switches react to sculpt your tone. This is iPhone audio because i'm lazy and honest. #guitar #amplifier #tubeamp
How did you remove C50?
C50 can be removed by carefully twisting the component CW and CCW until the leads disconnect from the cap but not the pcb. Much like how you can remove an SMD cap. To get it flush on the board, you'll need to lift that side of the main pcb to solder the bottom
Excellent technique. Thanks for the quick response!
I just looked at website. They have a kit for the tube M49. It’s on back order now but I may order two kits when I can.
awesome and funny...really love these guys... liked and SUBSCIBED !!.. KEEP ROCKIN HOSS
Unrelated question on this amp -- Is there a place to find descriptions/meanings of the relay designations in the schematic: RYTS; RYOD; RY2; RYE, RYA, etc? I am looking at the preamp schematic and having a hard time understanding how the signal flows in any given mode. Is this correct for clean channel in clean mode: Input --> V2B --> CH1 Tone Stack --> Ch 1 "Gain Control" (1 MA pot) --> V1B? And then "crunch" mode of channel 1/clean channel would be: Input --> V2A --> CH 1 Gain Control --> V2B --> CH 1 Tone Stack --> V1B?
I don't have the schematic handy right now, but Mesa has a pretty bad reputation for their schematics. Sometimes going right to left for signal and poor descriptions etc. You might be correct but I recommend injecting a known signal (sine wave at 400Hz for example) and then probing through the amp at every stage to make sure things are correct. I did a similar walkthrough with my own amp in this video. ruclips.net/video/1PB1vcr_Zik/видео.htmlfeature=shared
It sounds fantastic. The sound could use some treble. I have a pair of the Scamp 01's but they're not as good as the Compex.
Yo what size are those floor toms?
toms are 13, 14, 18, and 20....massive!
I heard Dave had a bad batch of caps early on
a bad batch should ideally be caught by the supplier before it makes it out of the factory to Dave, in any case, I would recommend a brand change!
Great work, I honor your intelligence, drive, and follow through. Will you be creating a product or selling to the DIY community?
thanks! right now I just build for myself, but I'm considering both options.
U47 for me is more soft and more slowly vs C12. The C12 is more agressive and fast...i hear with Focal solo 6
Interested in buying a board from you. I think I'd build this but I want it as quiet as yours
I should have one board still available. I'll reach out via DM.
A nightmare to repair.
Great build and video ! The U47 body come from AMI ? They seems to not sell body with pattern switch...? Thanks
yep i purchased everything from Dennis at AMI. Maybe sourcing those exact parts is difficult to keep in stock
Yeah, it depends of the stock, and the capsule is the M7 Thiersch PVC or mylar ?
Sorry, signed in correctly now. About those boards... :)
Hi Jeff, sure thing. I'll need to check how many I have left. I'll send you a direct message.
Thanks for the vid, Eddie. Can I purchase 2 of your boards?
Wonderful stuff! So informative! I just learned so much about the innards of guitar amps in 7 min 💪 Thanks for the content Eddie!
That’s actually sick
lol 2017 2018... i'm 1963
what gauge of wire did you use for this build?
30AWG-Silicone Stranded Wire
@@metalhead3ecr can i pick your brain a bit about the u47 build? is there somewhere i can message you?
@@artvandelay4914 go ahead and ask any questions here in case others have the same ones
@@metalhead3ecr first thing i would ask is, is there anything you wish u knew before you built the 47 mic? or anything you learned? things to watch for? I have ordered one my self to build
@@artvandelay4914 just take your time with the build and you should be fine! Things to watch for would be maintaining a good ground between the housing and internal electronics in addition to keeping a tidy workspace so no debris gets near the capsule or high impedance sections. If you ordered from Dennis, make sure you get all of the items you ordered. I never received the wood cases and had to ask for a partial refund a few times before getting one.
really cool seeing the process
Just picked one up. Total 80s beast!
3d printed?
nope! cast and resin. check out my other videos to see the process
very cool! @@metalhead3ecr
Is that what TAme Impala used on the early albums?
i'm not sure! sonically it's pretty close but I imagine Kevin used alternate gear for the early records.
No, it was a dbx 165. The ADR Compex used to be the compressor on the old Helios mixers, used most famously by Led Zep. You can here Bonham here, even though the drummer is playing quite soft. Amazing piece of kit
Nice to see someone actually demonstrate why transformer orientation and placement is important to reduce coupling. (Just think how low it would be with a switching supply!) Also like that 1) you have a good quality scope and 2) you have it in high resolution mode to improve the effective bit range and lower the noise floor. Oversampling each point in Hi Res makes a huge difference. Weird how RUclips got me here. Happy it did! (You could do a voice over on this one if the mood strikes you one day, but the vid does speak for itself..)
Hey Eddie, thanks for doing this, I like what you're doing and I'm currently working through my tone on a total rebuild of a Traynor YBA I've owned since the 80's. I'm at a point of doing similar tone tweaking, so it's right where my head is at. Also good to see the integration of the software and parts sourcing. Any thoughts on the Chinese component quality vs buying from Mouser, Digikey etc. Totally agree on the PT replacement too. Thanks for sharing! Much appreciated.
thanks for the comment! I haven't had any issues with LCSC, they tend to have most parts available. Fancier ICs from Analog Devices and Texas Instruments might be missing or low stock compared to Mouser and Digikey, but the basic components are usually well in stock and they have similar brands to what most prefer, Nichicon, Murata, Panasonic, Dale, Vishay, etc.
It went from squeeky mouse to growling lion.

Hey dude! Just watched your mic videos 🙂 not sure how close they sound to the “real” things as I haven’t really heard them myself, but they sounded good either way! I definitely want to expand my mic collection and I love the idea of DIY. What amp types are you building in this series? As in: which models are you emulating, or are you trying to do your own design? Is it a money saver like how the mics were?!
Thanks for watching! The mic series was more DIY as the originals are so expensive. I also haven't had the luck of hearing originals but these sounded killer and David Brown confirmed that they were up to snuff with originals he's repaired. For the amps, this is a different focus. I have been building amps since 2012 or so and have around 20 amp heads from other brands. It's a bit of an obsession. So this series, while not the best quality, is more a build log for myself to keep track of my progress. Not the most entertaining to watch, I know haha but it helps me document the process. I will add some voiceover in new releases. I plan to add more detailed videos explaining what i'm doing and what tone i'm after, but these first 5 amps are going to be for sale when finished. I tended to splurge on parts, so no corners cut!
@@metalhead3ecr I think it’s interesting to watch still, but you’re right that I would want to understand or know the thought process/what’s involved like you did in the mic series. Either way, thanks dude! 😁
Far out thats loud. how is it WITH the baffle in?
U47 is soooooo great
I like the way the sharper transients seem to "bloom" with the 47. The 12 is super clean thou.
Good Stuff!
Thanks for the vid! Will it sound actually good?
there are sound examples in this video and in my part 2 video.
im into this … love to see more
Great job my friend! Keep the covers coming!! 🎸
Thank you so much for taking the time to do this build and film it for us! I wanted to build one of these kids for a long time.
Great that you took the audio direct out from the amp - that's how it was intended to be used. Too many people either run these through normal guitar speakers when they are intended to go into a flat board.
Tread lightly?
yes! although executed poorly haha
Stock exhaust vs. needing ear plugs to ride a bike.

How to say I've never had a performance exhaust
