Ampeg Reverberocket tremolo increases signal

[EETStudent]

Im still having issues regarding the tremolo in my '67 Ampeg Reverberocket. When I engage the tremolo, the overall signal is boosted pretty significantly. I feel like this is not by design. I don't have a schematic, but mine uses the 2x12ax7s and 6U10. Any general thoughts on why this could be happening?

Here. Look under AMpeg, Rocket series. See which one looks closest to yours.

Aside from this, does the trem WORK?

The tremolo is a variable resistance (photocell) in series with the signal path. The intensity control is just a pot shorting across the photocell. With the pot at zero ohms, the photocell has no effect. With the pot maxed, the photocell has max effect.

If the bulb is stuck on bright, then the volume is also maxed. Is your bulb cycling on and off?

If enzo got it right. A first test could be a signal jumper over the pot.

Enzo,

Here is a link to my schematic - Ampeg gs-12r image by Travst on Photobucket

It was easily tracked down by googling GS-12r schematic.

I have not visually checked the photocell, but it sounds like that may be the issue. I'll look over it
