Oh, a C2 of 0.68uF also works and will give an Fc of ~15Hz but I didn't have one on hand.

Okay so after three different itterations I'm finally happy. To replace C2, I put in a 1uF 400V cap mounted on the underside. [Not acting as a HPF for the Dry path with an Fc of ~10Hz]. Then, to make a HPF switch for the Reverb Wet signal only, I cut Pin 3 short and mounted it via a 15nF cap...

I’m now working on applying the Fc switch to the wet signal but not the the dry path. Been busy lately so slow progress.

Oh, by the way, I'm in the middle of trying different values for my coupling capacitor. I'm still not happy with mine (the fc of the voicing switch is still too high). The capacitor C2 sees a total impedance of ~15k4. (The Plate output impedance of ~8k6, the following resistor network, and the...

Very cool. I've never tired SMD before. Hmm

Very neat work Rpschultz13! If I may ask, what is that small blue board on the bottom left?

Okay, so not a drop in replacement, but will need to be moved to fit in the deeper MN Pot. Hmm…

Great call sir! No I was not aware of these. So… how much of a change would it be to swap the current mix pot with the MN taper pot? Perhaps a matter of changing the pin configuration? It could be relatively simple!! I’ll have to have a look next time I’ve got a moment… The Vol pot will still...

I know, right!?!

I had considered this. In the end I decided to use this build as a learning experience. I’ve never used op amps before and am enjoying the learning. :) I know it's expensive, but if I learn how to use the OPA2134 dual op-amp it'll open up more design possibilities for me. My current inquiry is...

Here is a video of my version of the BTR... you can hear the three different voicings: From Bright, to Middle presence, to full Bass. With the mix turned all the way down, you can also use the BTR for a bit of tube buffering/compression/dynamics as well :) Thanks to MarloweDK for the bass loop...

I still haven't decided where the Tap LED should go.

This is my project thread to invite comments / mockery *cough* shared laughter or any input readers might deem worth while :cool: Here is my draft graphic of the Effector against the Reverb I have yet to label the three way switch at top left. It will be up-Reverb, mid-Delay, down-Chorus. The...

Borrow my pics as much as you like… since I stole the whole idea from you 😎 But I AM working on a Bathtub mod to use the ABE module! I’ll post if I get it to work.

So now I have to buy an Ambassador board with my next C2CE purchase 😁🤣

Nice work TillMack!! Looks great :) I've had the same trouble, often the pots have a small tab which need to be taken off. I just do it automatically now as I don't like how the tabs tend to skew the pot's alignment. Also, when using a powder coating and face-plate, I would sand flat the pot nut...

I suspect it is because they only need to manage the voltage drop across the resistors which is much less than the 250v plate voltage to ground.

I checked the resistor values in your pictures and they look good. I don't have a Nobelium with me at the moment, but these are some measurements I've taken previously.

Does one of your output jack tabs touch the enclosure?
