Feedback question

Postby blackwatch26 » Thu Dec 28, 2006 1:20 pm

Shannon, Would it be possible and/or advisable to adapt a variable feedback as in the 35 with the Poseidon?

My Mark III clones are usually in strapped triode with high efficiency Khorns.

Everything is possible! Yellow_Light_Colorz_PDT_06 Are you looking to switch from triode-some-feedback to triode-no-feedback? Or an adjustable pot?

Preferably with a pot like on the ST-35. I like that feature a lot.

Well, if your amp is stable with the amount of feedback you have now, you could just add a 50k pot before or after the main resistor and bypass cap. Should work fine.

That's easy. Thanks Shannon.

I eagerly await my Poseidons.
