Rockster Reverb combo project

On Rj's layout above it should be relabeled

B+3 should be B+5
B+5 should be B+3

B+5 feeds the V1 tube it is the last filter cap in the dropping string.

I have notice labeling is reversed. So just do it like on the layout and use B+5.

Thanks

I have installed reverb in my rocket build, is it me or reverb circuit is changing tone of the amp a lot? The amp is missing high freq and I tried to disconnect 500pF from pin2 of the treboe pot and amp is more bright like it should be, is that normal?

I would go back over the layout/schematic and make sure you have everything wired correctly.

You should have nice chimey vox tone with subtle reverb.

I usually always play with bright switch on if you have one otherwise it's usually wired to the volume pot by 100pf mica cap.


The 500pf treble cap needs to go to pin 3 the entrance of the treble pot.

I have followed all infos on the forum about adding reverb to it. So reverb circuit is entering on the pin 2 of the treble pot if I am right and first part is 500pF cap and when I disconnect that cap from treble pot I have more chime. Also I have bright switch and it brings highs back, but tonestack is behaving differently..

Right, there is a 500pf cap from V3 with 220k going to one side of the PI entrance. You connect where the 500pf cap and 220k meet.

The reverb pot is connected to the other side of the PI entrance and also to V2.

It definately is changing sound, but it can be compensated. Here is clip made with mobile, so you can hear how it sounds..

You had the bass off per knob setting but the amp sounded good to my ears.

Thanks Mark, the amp has quite a lot of bass. I guess that is normal. Cab is 212 Wgs veteran 30s, open back.
Also I will probably leave reverb tank outside, because it gets noisey when I put in in head cab.
