Regarding the JCM2000 DSL amps, do they all have a hum? I've been through several forums, and I get a mixed opinion. Since the PT is a laydown type with the connections inside the chassis, unlike a stand-up style where wires run through a hole, I can see where hum is introduced. The hum doesn't change with volume or eq adjustments, but is there in the background. Any thoughts on this?
i just had a DRRI that had treble pots going almost to ground on wiper,washed them well with cleaner and now it seems fixed,probabli it's the same issue with whiskers,amp from 2010
once you get old as a tech you try to avoid all the BS you've been trapped in in the past,rule of thumb is don't work on stuff that's not worth it,don't deal with people that try to devalue your work asking discounts and keep chatting until they get the free consulting that won't be used anyway-. I wouldn't blame any old guy for that.
Well the problem with PCB-based boards and non-standard...turret, ST1 (1987/1959/1974, etc) is...especially the first time, you have to figure out the design to service it and guitar players don't get it as not technical, but you have to research and find schematics and things which can take hours and experienced techs and engineers like me, Bruce, George, etc...that rate can be $60-100 per hour! So, if it takes 3 hours of our time just to get an understanding and disassemble, assemble, maybe check tubes on a tester...is it worth it when you're working on a cheap ass amp like Peavey or 5150, etc.?? Not really worth either the tech nor consumers time and money. As stated, if a customer is willing to way and pay a premium...SURE....we'll do it. It's money. But 99% of the time, Pass. Better off finding a teen or someone in college say studying engineering or a tech and pay them $15-25/hr rather than professional fees.
If you had Marc on it would be very bland.. For being a host he doesn't have much vocabulary. " Thats cool" or "awesome " would be the only thing said lol
Must push back on your consistent rant against Mercury. Yes, more expensive but where are you going to go elsewhere to get a vintage transformer with accurate construction and has the same spec as the original? You don't think having the blueprints on hand for all those old (valuable) amps on file is worth a premium? How the vintage transformers were made, varied ALOT back in the old days, so unless you are a transformer designer with vintage experience it is silly to dismiss the expertise that Mercury offers. Agree as a manufacturer mass producing amplifiers, that Mercury may not make sense but in the arena of vintage amp repair. I find Mercury pricing to be top quality at a fair price. Also consider the convenience that most of the Mercury iron is in stock to ship out same day... just saying!
Heyboer are just as good and are cheaper. I don’t dislike Mercury and have no axe to grind here, I just don’t understand why anyone would pay more when the same quality is available elsewhere.
never tired to listen to these guys wisdom,thank you for the time well spent!
Absolute joy seeing all these tubular geniuses get together, cheers!
Thanks for tuning in!
I agree with the digital/tube comparison by Dave
This is a great trio. Need to do this on Tone Talk too.
Renegade is a great amp. If it has little bit more gain , probably it would be perfect

Tommy Folkesson makes killer mods too!! You should invite him to a talk!
The Hook Wizard amp is the latest amp I can think of that uses digital controlled motorized potentiometers.
How about rob Robinette as a guest? Uncle Doug would be fun. I wanna see uncle dogs cars.
How this thing called? 19:00 the power supply for heaters etc. on Mouser. Thanks!
Recom
I'm don't know for sure, but it might have this Mouser part number: 490-PSK-20B-S12
What was the Optoisolator Bruce recommended for use in a mute circuit in the 1st Bruce/Dave chat?
h11f1
just look at Egnater schems in general
@@MrAletube thanks man!
Guys im in the UK
What transformer manufacturer would you recommend for us ?
Try Michael at Modulus if you’re after one off sets.
@@HeadfirstAmps thankyou very much
It looks like the new Soldano Astro amp has digital switching
Midi switching is a good thing.
