More readings...it seems that the DC offset jumps past 100mA as soon as I try to adjust the volume, it settles back down again after a few seconds. Since I'm new to all this I'm interesting in hearing some ideas on how to solve this.

He sends a pricelist of options. You can omit anything you don't want.

Anyone here try 6N2P tubes in the SOHA II? When I put mine in, I can only barely turn up the volume and then the amp cuts out? Any ideas?




6n2p are similar to 12ax7. I believe these are too much gain for this configuration. Do you have any tubes known to work with this circuit?

jjazzyj, tacitapproval is correct. If those particular tubes are similar to 12ax7 they will not work for you. If you can get something closer to the 12au7 the e12 should settle down.

I'd been doing some research about the 6n2p and yeah, there's too much gain. They don't sound that great in the SOHA II when they're working anyway. I like the little bit of extra bass they have compared to the GE 5963, but the rest of the soundstage is muffled and dead. I don't mind the 5963 that came with my kit. Just wanted to try the 6n2p out.

You could also try Amperex Holland orange globe 6DJ8. More bass than my 5963 and Sylvania 12AU7.
