Hoffman Princeton Reverb Trem-O-Nator Upgrade

Ah. Yes, unclear. Does "9.999Hz" mean it barfs on 9.998Hz? Or just give degraded (from 0.001Hz) accuracy? (Nearest-Hz is plenty good for us.)

No frequency response on ACV, however AC Amps is rated 40Hz-400Hz with about 60dB (1000:1) precision. Unless that is some steep rolloff, you'd expect some reading at 4Hz, even if only 1/10th of correct.

Is a much better amp-bench meter than I'd feared, but still KLEIN is a electrician supply not an electronics-tech market outfit like HP or Heath were.

Tremo-No

Getting back to the Princeton Mod.  Any new thoughts or things to try?

Wondering if I should rebuild it and move on.

Yep. Turn the page.

I've been reading every post of this saga cause I plan to use the Tremonator in my 6V6 plexi build and struggle with the best way to connect the intensity pot. I love the Princeton Reverb but it has barely enough preamp gain to make the reverb recovery work. The bigger Fenders have a mixing stage dedicated to making the wet/dry combined signal large enough to drive the phase inverter. There is enough gain left over to drain excess to ground through the 50k trem intensity pot on the Tremonator or on the original trem circuit. But connecting a 50k trem pot to the Princeton drains away too much gain.
So...how would it work to cut the Intensity pot ground wire? One of the guys on the Dumble forum did that on his Dumble clone. See attached photo of his schematic.I'm counting on his solution working on my Plexi clone (in process). But I'm still a long way from testing it for myself. So I'm hoping that you or someone else farther along will try to replicate his version of this great circuit.

I'm wondering if the Vactrol was defective or weak in some regard?  Do you have another one you can try?

I would rebuild the tremolo and get it working?  I just put one in an amp & it worked flawlessly from the get go (which surprised me). 

With respect, Tubenit

I did try a second Vactrol component without success.
