The Amp Garage

Hello, I am wanting to experiment with making an active FX loop and have found several designs leveraging the LND150 MOSFET. However, they are clearly difficult to find from the usual suspects. Everyone lists them as on backorder. I have found a few on ebay at inflated prices from China, but am afra...

I’m planning to build the BE50. Any recommendation with Power Transformer? I’m having hard time to find Classic Tone Universal Power Transformer. I’m looking for a recommendation or idea on sourcing Power Transformer I just built one of these for a friend and used the Hammond 290GX PT. I ended up d...

For reference here is a finished shot of my build so you can see how the cap cans were installed. This matches the original layout

My layout is incomplete in the OG one posted. I didn't really finish that section out since it is the same on all my amps I've built and I go from memory. In the spirit of giving back I updated the drawing to be correct and attached the new version. The perspective is from the back of the IEC.. The ...

Well, I already built the turret board but just purchased the FX loop board and got the drawings. Great implementation on the Double Shirley. May need to add that down the road.

Thanks!

That would be harsh

oops all the couplers PI and out are 100nF

(.1u like a JTM)

He is correct.. I mislabeled the schematic. It is correct in the layout at .1u. I updated the schematic with the correct values.

HTR CT goes to that 470k/82k divider (raise heater DC ref level) plate cap on PI should be 47pF missing 1M across master good catch.. I saw the elevated heater CT but didn't even think that the divider was for that. I assumed it was a convenient place to put it. lol I have fixed the other issues in...

Greeting TAG, First off, I appreciate the amount of information on this site. I came here a while back to build a Dumble clone and have been sucked into the rabbit hole. FWIW my #124 build came out amazing, still tweaking a few things, but its a really good amp . I've been building amps as a hobby f...
