I have 2 routers I use for wood, I should be able to use a router on a stompbox to take a skim of the front thickness. I am guessing it would be easiest to do it from the inside, I have to research if I need a special router bit first or if the wood ones will do. I might have to make a jig to...

I think that would be enough for just a small power amp at up to 1 watt, as I mentioned above there have been some success using PA 100V audio transformers as output transformers. The PA transformers are usually very cheap and have a much better frequency range then normal output transformers as...

That seems very strange, the only thing I can think off is that you have a faulty switch. When you have the pedal off can you put a small jumper from 1-2 on the switch, or just check with a meter if 1 connects to 2 on the switch with the pedal in the off position. In the off position the input...

Good to know that Taydas 1590DD is too thick walled, but the drill template would still be great to have in case I want to make a fascia PCB. It would also be very useful so I can mark out the holes on whatever I will place it in, I prefer the dimensions like you have left at Tayda because I...

Vigilante398, do you have a Tayda drill template for the Supersonic? I think that one might be a bit hard to do by hand so I will have to get one made. I might also make up a fascia PCB for it so I got one when I am ready to order the Supersonic PCB I don't know how Tayda ships so cheap to Au...

Here is the drill template from Tayda, all dimensions are from the middle of each side.

It would appear that you have a broken trace on the switch PCB in my opinion. Pin "C" is connected to pad "5" by a trace on the PCB and pin "D" is connected by a trace to pad "6" on the PCB so there should be no difference when testing C-D or 5-6 with the meter set at mA. The good news is you...

If you do find a smaller cheaper transformer I would love to know what it is, I also would love to make a tiny amp but I would like the pre-amp in one stomp box and the amp in another stompbox. I would drive the power amp with the Sushi high voltage SMPS power supply, I already have the Bassdude...

Can you check the voltage between pin C (5) and pin D (6) on the switch PCB, C is the earth and D goes to the 1k resistor and then to the LED and then to VCC. In bypassed you should have 9-12 volts, and then 0v when LED should be on. You can also test the LED's current draw from C to D, when...

This is a small story that might inspire you to look at other types of transformers. https://www.ozvalveamps.org/optrans.htm You might be able to find more info if you start there and then let google have a go at finding more.

Not for a normal RAT, but since yours has a tube buffer after it it might still be nice, I would have to build one to know but I have some normal RAT's laying around and if I was going to make another one I would want a FAT and a BASS mod done to the HPF at the OP Amp since I now have Guitars...

Or middle can just be like a nice buffer as long as you don't crank it into clipping the OP amp.:)

Up appears to be the LED's to me, just my opinion. If you zoom in on the build doc you will see the switch is upside down with 1 on the bottom, switch up closes 1-2 on the switch. I wish there was a Bass/Fat/Rat switch for the HPF on the IC, it just needed one switch SPDT ON-OFF-ON, one cap and...

`I just checked the PCB to the schematic, component ref's do not match so follow value on PCB's I would say. 27k resistors should be 2 off (R1,R2 on PCB) 47k resistor should be 2 off (R5, R6 on PCB) 1M resistor should be 1 off (R3 on PCB) All else seems fine to me. Cheers Mick

Before I build any PCB I have ordered I usually trace the PCB to get the schematic, I get a better "feel" for what I am doing that way. I have traced the Bassdude and I think the circuit is a copy of the 5D6A Bassman, nearly everything matches apart from V1 was a 12AY7 in the original. A 12AY7...

I would love to see the schematic on that 3 watt amp, I would love to build me a small tiny amp and run it from your HV power supply. I think I mentioned it in a PM I sent you that I would love a tube amp pedal for home practice that I can run from the Bassdude or Nobelium, 1 watt would be great...

I would not call that a tube compressor, 99.9% solid state.

I presume you mean 10nF and not 10uF, I get 72Hz with that value. Here are the frequencies I worked out for my mod in post 239, best to do your own calculations in case I am wrong though. C8 value in yellow column and the frequency is next to it. I am really interested in what you find out.

If you want an old school sound build a tube tremolo https://forum.pedalpcb.com/threads/mirage-tremolo-tube-tremolo-project.21546/

Try this calculator :http://sim.okawa-denshi.jp/en/CRhikeisan.htm It's a great place for calculators but it can get a bit techy. The Nobelium does have a 6dB/octave HPF, my mind is playing tricks on me again.(Fixed above post) I thought that the frequency should be at the -3dB mark when...
