The Amp Garage

Well garsh, color me blind. That must have happened as I was trying out different slope resistors. You are a life saver, I was going to button it up and live with it. Thank you

I replaced the cap and it has some effect, but I guess I never realized how little the tone controls have on the shaping.

Loop circuit is completely removed from the amp and still no treble control. I checked the pot and all the tonestack wiring. Stumpted

Ill check those, thanks

Bass and mid pots work

I have a 1987 20watt clone that I built last year. I put in a Merlin tube effects loop and a lar mar master volume that stays full all the time. I get a nice mid heavy, brown tone, which I like, but the treble pot seems to have no effect at all. Presence and bright caps help but no treble bite from ...

I have attached a schematic and I get ranges of B to Gnd 3.43-3.66 E to Gnd 0-2.42 C to Gnd 3.59-3.91 when turning the 5k pot. hFe is hard to pin down, all over the place on my meter.

Hello, I've just built a rangemaster circuit using a ECG160/RCA SK3008/Motorola HEP637. The unit works but I'm not sure if it needs tweaking to optimize it. Here is the spec sheet for mine, how close is this to the OC44? Thanks

So I've successfully built and implemented this loop circuit. My question is which tube to boost the return, ecc832 or ecc823. I just need a double check but I would think the latter.

I'm interested in an LD150 one I can use in my plexi clone. What is your price, shipped to 53085. Thank you

Does anyone have pcb for high voltage effects loop

Thanks for the layout

Maybe it's my layout, but I'm going to put my soldering iron down and just ply for a while, I might go back to it on a wintery day.

With plain old passive loop, I can run reverb and delay, but I run flanger and chorus in the front door. The loop HATES my chorus. I don't use overdrives anymore because the amp itself is overdrive heaven.

Why yes, yes it was. so far a waste of my money and time
