Deluxe Reverb Normal Channel Low Output?

Post by theundeadelvis »

Hey guys! I just finished a Deluxe Reverb build with a bias tremolo from the 6g16 vibroverb. Everything sounds pretty good except the normal channel seems a little quite to my ears and isn't breaking up much. It sounds about like the Vibrato channel on 6 when it's dimed. I've quadruple checked my wiring and it seems fine and I've checked my voltages. Any suggestions of where to look? Thanks in advance!

run a signal through it ...... say 100mv 1k
and measure the signal at various point along the signal chain
see at what point the signal strength really diverges from the expected

Hmmm, I don't have a signal generator.

I’m thinking this is to be expected. Assuming you are using the normal 3rd stage on the reverb channel, it should be louder and have more gain. Since you are not using the roach-type trem on it, you are not continuously sucking some of it’s signal to ground. Many people add a switch to the trem control to prevent the signal suck from the roach approach.

Sounds like a good idea and a success. What value cathode cap is on the 3rd stage of the Reverb channel?
If it says "Vintage" on it, -it isn't.

If I understand correctly which one would be the third stage then it's 25uF. I'm still learning this stuff so I'm not positive. I just know enough to be dangerous.
