Re: Reverb on Normal Channel

Doc | Re: Reverb on Normal Channel The is the way I do it: Jumper pin6 of V1B to pin6 of V2B with a piece of insulated wire. The outputs of both preamp tubes will now go through the reverb circuit before reaching the phase inverter. Both preamp tubes are supplied from the same B+ point in the power supply, so it's ok to connect the plates directly. Remove the coupling cap (.047uf?) coming from the plate (pin6) of V1B. It's in series with a 220k signal summing resistor, whose other end connects to a similar 220k resistor on the component board. You can leave the resistor in place, open-ended, or remove it if you like. (I like to leave it in place for an easier return-to-stock wiring locator.) If the sound seems brighter or thinner than before, you can exchange the loose .047uf coupling capacitor for the .022uf one connected to pin6 of V2. Hope this helps. |
