tube effects loop schematic

Post by beasleybodyshop »

Anyone use one they really like? I want to add a loop to my JMP clone, and I want to build it instead of buying one from metroamp or weber.

Any suggestions?

Originally a Triad R-2C, long out of production. David Allen's TP2X is a good replacement using a FWB, and it will fit in a 1u rack chassis. I used it to make a stand-alone D'lator here: https://tubeamparchive.com/viewtopic.ph ... highlight=
Do you want to add this loop to an existing chassis? if so, you can tap the existing power supply at the screen node with two R-C and make two new nodes for the loop.

Here are two more variations on the all-tube loop. This is going to make choosing one difficult.
