dbx 161-Mods
Working on two of these beauties right now. Nice design, nice PCB layout. The customer wants new caps, a few power supply repairs and to add Jensen input and output transformers to these normally unbalanced units. The 160 (the famous unit) uses the same PCB as the 161 but a has a solid state balanced input and output circuit populated. This mod, IMO, is way better ;)

Roland RE 301
Well here is unit that may sound great, but the build quality is really not ideal. This monster ate a lot of time, but with a complete re-caping and few transistor replacements and relaped heads its looking up for this classic machine.

Klark Teknik DN 34
I also had a chance work on this finely built piece. This unit is very cool for making subtle delay/modulation effects. The unit on the bench had a blown output amplifier. I added a opa627 with a slight modification and she is working again.

Altec 436A Resurrection.
Brought back to life, the oscilloscope pic show how it arrived (that was its output with a sign wave on its input). I recapped the unit, added threshold, attack and release controls. Now its is a pretty amazing box.
