  • This is a review and demo of the DIY tube amp kit KLD JCM-PC which is a printed circuitboard do it yourself tube guitar amp with the same circuitry as the Marshall JCM 800. This one is a little different since it's only 25 watts, has a built in attenuator, and has a DI XLR output. Here are the links I promised in this vid:

A bit more mod friendly than PCB, and the traces will never fail if you're new and overheat something - can't imagine the PCB is very rugid, but that's not the point. $300 for any amp kit let alone a 2204 is damn cheap.

    I know it's been a while, and I appreciate the content. When you're building, considering putting together a variable output transformer or a voltage soak (using a lightbulb) so you can test for shorts and whatnot before you throw full 120v power at a build. Not sure if you've done that since. The bulb method is way cheaper, and it will literally light up very brightly if you have open shorts like that while protecting the equipment.

    KLD fills the void in providing a large variety of amp kits that allow studio, jam and stage micd options. The fact they sell an Ampeg Portaflex clone is awesome. In my experience All my 100 watt mesa and marshall amps Even at large clubs or out door gigs. Never turned up past 4 or 5. Actually sound guys got pissed about being too loud. So these 25 watt kit amps let you expand your amp collection. Ive built tube amps from old tv parts other kits. Fun projects that sound awesome. Gonna make several of these KLD kits. Lots of room for modding. If you look around tubes can be found for reasonable prices.

    @ 4:15 is why the old school techs in my old radar repair shop had a pet name for l the first time we applied power to a newly repaired component of our radar set. We called it the Smoke Test, or Smoke Check. It may also be used as a verb. Example: "Did you Smoke Test that ASR Transmitter yet?" The past tense would be: "Why, yes, I Smoke Checked it this morning before the Air Traffic Controllers arrived to break it again." Finally, a message from the National Dyslexic Bass Players Foundation:
    "Dyslexic Bass Players Untie!!! Or just swap those two wires and Smoke Check it again."
    Thank you very much.

    Yes, a bass amp kit is something I have been wanting to find for some time. The pricing on the full valve bass amps are just out of reach for people like me so a kit would be ideal. Fortunately I believe that converting this kit would be relatively simple as the differences between guitar and bass amps are mostly in the pre-amp and gain sections. I would love it if they could engineer it to match the tone of the old Marshall 1992 Super Bass head - that would be perfect for some Motorhead style goodness. Especially since Marshall don't even seem to build bass amps any more.
    The cheapest bass valve amp (not hybrid) I could find out about is the Ampeg PF-20 T for £529. So if KLD could make a bass amp kit and stay below the £200 mark like they have with the kit in the video it could be a real winner.

  • @geralddenavich8783
    @geralddenavich8783 2 года назад +5

    It's a nice build but I ordered a kit from them before and they are not true clones. They don't use tube rectifiers and chokes so the sound is much different than an exact clone. Plus the jacks, pots, caps aren't the best quality. It's not an easy thing to build an amplifier and using low quality parts just complicates matters further. Also, the pre soldered wires were way too short to run them correctly. It's important to run the plate and grid wire properly to eliminate noise and the wire length just isn't there to do that.

  • @shawnhale2631
    @shawnhale2631 3 года назад +1

    So since it smoked, definitely check the caps and low value resistors. It's probably still working because they were bypass caps, or PSU regulation and there's just a smidge more noise than there would be. (I'm sure it's as quiet as you say, but something to do!)

    • @GunsandGuitars
      @GunsandGuitars  3 года назад

      When I was troubleshooting after I smoked it, I did check the resistance on the caps and they checked out. Someone else here mentioned that the smoke probably just came from the diodes and therefore didn’t affect anything else (I don’t know enough about this to know if that’s true or even makes sense) but I can’t find any damage and it definitely makes less noise than most other tube amps I’ve played on (part of that could be that I got a good set of tubes this time).

    A 7025 is basically the same as a 12AX7 or ECC83, it's just a lower-noise equivalent, Fender use them a lot as the V1 in a Fender amp's preamp circuit.

    About 4 years ago I bought the assembled Pilot 15H, used on eBay for under £90. The UK distributor was then selling off the rest of their stock so bought a new PVA18H, the handwired Marshall 18 clone, collected direct from their warehouse for only £165. Since then there has been no sign of them in the UK. I run a small festival where I provide backline for all the acts. I offer a VHT 12/20RT and these two heads plugged into a couple of mini stack of 1x12s. Plenty of volume to cope with a heavy handed drummer, and taking the XLR line outs direct into the PA they sound great. An AC15 style head would be interesting.

    I had something similar happen when I built a kit, your transformer will start to make noise (the one that smoked) over time. If ya tighten the screws on the transformer it will make the noise sort of go away. But when that thing smoked it did indeed to do damage.

      @HandWiredAmps 3 года назад

      Looks like the IEC (electric plug connector) socket is fused. I don't see a fuse for the secondary (high voltage side of the transformer) on the schematic. You could add one or two.

  • @sc0or
    @sc0or 2 года назад

    6L6 can typically dissipate 17W (30W as an absolute max). This is about the same power as goes into a driver. And the transformer is pretty small for 25W. I'd suggest the amplifier gives about 15W (with 10% of THD). Which is not a big difference.

  • @matthewbudner2762
    @matthewbudner2762 3 года назад

    I built the older version of this amp last year. Had some major issues with the diagram (me dumb dumb with electrical) and it was the point to point version. Zapped myself a few times, effects loop and xlr don’t work, neither does the presence. But, the gain on mine sounds great, and it takes pedals like a dream. It was a great week long project, and it does work over a drummer, though the hum from my terribly twisted heater wires was pretty present.

    you should do their 5f6A bassman kit instead if you were wanting a bass amp? As far as the chassis goes and KLD making changes, good luck, I had the same issue with the 5F6A kit, neither the JCM or the bassman kit are new to their lineup. Also , your not the only one with a diagram issue, the bassman kit I had to contact them and point out they had the wrong diagrams uploaded for the 5F6A kit, Yes they sound great nice and quiet, but crank up that presence knob and you'll get a different story. Their "handwired"kts are the exact same just preassembled.

    Nice!.. Whoa, two years on, guess I missed the Memo :) Tube Bass Amp? I Love it (did they MAKE one?) Only.. What would be the defining difference? I mean Lemmy used a Marshall right? What would make a BASS tube amp different? Here's my 2 cents (something i actually made)...
    This wasn't me building to purpose, just a dirt poor (things aint changed much) squatter wanting SOME kind of amp - started with this EL84(6BQ5) railway station Public Address thing with a 100v line out tap - I ditched the tube rectifiers (sorry, can't STAND 'em) put in their place an extra output stage, so I had double the power - then gradually changed the guts around, more gain, bigger opt (I kept the original one - liked the sound of it getting saturated) and lower coupling C's - THAT turned out tricky as HT(B+) volts would swing all over when i hit a note, so i stabilised Pre HT, used BIG HT(B+) CAps per stage, and a some grid stoppers to limit blocking disto4rtion, I was VERY fond of the thing, yet sadly it got destroyed with a bunch funky junk in a nasty ol' London Eviction..
    I had a Vox for a while (a scrap chassis i found junked) and it was interesting how I'd made something similar - hot biased EL84s, only THIS thing gave WAY high HT volts, and the Tfr sweated from running basically 2 amps lol - I changed it for something more sensible rated, but I preferred the sound on crazy voltage (the NOS Tubes could take it - only 'NOS' as I got my stuff from junk and thrift shops!) i wouldn't reccomend trying it with today's tubes (if you do, try 'n keep G2 voltage below 350 huh?)
    I'd dig recreating this if i get some interest... ?
    Maybe with 6L6GC or EL34 as this would be a mite underpowered for most folks - sure sounded loud to me mind ;)

    Not many electronics components work well after they produce smoke, most of them do not even work at all. Did you check voltages after that? Were there any instructions on measuring anything after building it? What I mean is that if you remove the treble pot for example, I am guessing the amp would still "work", that is, it will produce sound but...
    Thanks in advance.

Best investment i ever made guitar amp purchase wise and i was only 12 when i bought it with lawnmowing money i saved up. But buolt the jcm800 last year like this one and soent close to a grand jaut on the head but it sounds exactly like a real jcm 800 sode by side. And my jcm 800 is a full 100 watt clone and i can switch it from 1watt,25 watts, 75watts and 100 watts all on one switch

      I used his 2x EL84 / 6BQ5 design for an output stage, but drove it with a Vox AC15 phase split and used the AX84 Hot Rod design for a preamp.
      That thing is a beast of an amp. Only 10ish watts but it needed an EVH speaker as the little alnico I had couldn’t take the punishment
