12AT7 REVERB DRIVER

Having that said, tone is not about volume. I also have a transformer that would be a good match for this and I’ve been planning to try it. I have read this tube will more powerfully drive the reverb transformer and tank send transducer. Recently I built the circuit but I used a I had by hand and I have to tell you the reverb sounds very acceptable despite that theoretically the OT should have higher impedance.

Some amps are sensitive and difficult to control the reverb on.

Good 12AT7 Tube for Reverb …

I had one briefly. I tried a 12AT7 in the same circuit and sounded weak at the recovery side which is to be expected. Diode rectifier — More clean headroom. A new cable opened it up.

Seems to me I have also seen – for want of a better term – differential drives where the reverb transducer was essentially wired between plates of a PI sort of circuit. I ended up removing the cathode bypass cap as well, I had way too much gain in the reverb return.

Log in or Sign up. In other circuits though, the 12AX7 might not have the power to handle the circuit around it. BobbyZJul 20, Does it go in parallel with the anode, the transformer, with both or what?

I think that you’ll find that Enzo’s comment is true I’ve used 12AX7s as reverb drivers simply because they were what I had lying around. By Amp Kat in forum Guitar Effects.

Reverb and Driver tube: 12AT7 or 12AX7?

We all know that speakers change their tonal character during age. Erverb is an important character with vintage amps, yet so individual and mysterious. Why would you spend good money on an audiophile grade tube to do this? Last edited by mooreamps; at How about as a phase inverter?

I was always curious how that Mesa reverb circuit will sound and if they are using their own transformer. What was Leo thinking?

AT7 has lower gain about 70 compared reeverb of an AX7. I’m no tube snob, just replied with what I’ve found to be a rugged and reliable and inexpensive by today’s standards tube.

If you think your amp and speaker are sharp and edgy this mod could be worth a try. Jul 21, 6.

You get the most effect of this revfrb by disconnecting the NFB loop entirely. Jul 20, 4. I run 12au7s because I do haul organs home when I can.

So does the reverb. Install the Mercury Magnetics OT.

In both long and medium delay, the 6 spring tanks were MUCH better than the 4 spring units. No, create an account now.

The Gear Page is run by musicians for musicians. This has a lower tube count, which is generally good. To tighten up bass means removing the farty, low bass frequencies which are not handled well in a low power amp like the PR. My motivation was to explore why two BF fender amplifiers I owned had very different sounding reverbs. For amps with reverb you could use the reverb footswitch phono plug if you are not using it.
