Re: A SSS Build
Nice! This motivates me to pull out my empty Erwin chassis too and get to work. What are the relays going to switch please? On my previous Erwin-sourced chassis I found those wing nuts stripped super easily after a couple of uses. I ended up drilling out slightly larger holes and using normal chassi...

Re: ODS Inspired Build; #102 Values with Buffered FX Loop
Great looking build Glenn
The OT phase test info would be a good addition for the FAQ section too

Re: Two Rock Classic Reverb Signature Schematic (Current Version)
Perhaps the gain structure switch may be the same one documented in this thread (although that says CLRS v3)? Repeating here: I checked inside a [Two Rock] CLRS V3, the gain structure switch is 1M/(47k/113k/80k) divider. Resistors [are] 47k,33k,33k ... It is place where the 68k/1m divider is placed ...

Re: Replacement for radio shack 273-1365
I see one recent build using the Hammond 166J6, for example, with the typical voltage doubler arrangement.
Hope this helps - good luck with your build

Re: Matamp R28 info - request for help
You’re welcome. I’m a little jealous even ;) The first tube amp I ever played was a Matamp-Orange. If you are able, and can do it safely, some decent photos showing the insides would be a good addition. Remember that lethal voltages continue in the capacitors for quite some time after power off, so ...

Re: C-lator hum
Another discovery!!! When the C-lator is on, there is hum while on both standby or off standby. When the C-lator is off, the hum is much less. But when I then remove the C-lators AC mains connected to the wall outlet, there is NO HUM! Can I just check: Are you saying here that having the device mai...

Re: Colgan’s SSS without reverb
I am really curious how this build turns out.
I’ve recently discovered the Phillip Sayce amp (Mother) built by a member here, which I gather should be something like an SSS or Dumbleland with the CF (based on comments I could piece together). It sounds immense.
Please keep us posted on the results.

Re: Help with circuit
Another idea might be to build a known circuit making use of your chassis and transformers if you can identify them by part number. You’d have a good chance of a successful result. Just a thought…

Re: Help with circuit
Hi The pictures on your other thread with the amp as you bought it give a lot of context. If I understand correctly, you’re replacing the original board with this new one you are making and then want to modify it a bit. Not a bad way to learn at all, and you’ll find people here are generous in their...
