wiring paralleled triodes

[Matty_V]

How do you run the wiring for a parallel triode? You've got 3 wires crossing paths, whats the best way to route them? I've got a beastly parasite to tame and might as well start here (the start!)

Three short wires connecting the pins directly placed on the socket itself.

Pin 3 to pin 8, pin 2 to pin 7, pin 1 to pin 6.

This is the same manner in which the paralleled triodes of a reverb driver are wired.

Hey Matty,

Beastly!?

is it a Push Pull power section?

may need to swap the plate lead on the OT.

Have you chopsticked the leads in your suspect area and have noticed a difference better or worse?

I've paralleled a few triodes, even had one that switched in and out in a high gain, but haven't had oscillations (that I know of).

Oh ok, I took a look at dougs picture of the reverb stout to check out how its done. I guess I was making too big of deal of keeping the grid wire up above the plate and cathode. The way I had it was making the grid wire into an antenna for noise.

It starts its vampire hissing around 1/2 up on the volume. Not sure why I haven't tried switching the plate leads yet. Maybe cause last time I had them swapped it wailed mercilessly right as it was turned on. How come one configuration causes such awful oscillations?

Hi Matty V, This is how i did it, kept the heater wire low with the plate wire over, then arched the cathode last.i used two grid resistors and each has its own 1M to ground. Thanks
