Thanks for the replies. I haven't had a chance to really play it, other than to know this amp is going to take me awhile to dial in. I like it but don't want to gush until I have actually got the sound I want to hear, but that is for another category. I biased it hot last night. Interesting, the pot to adjust has no slot for a screwdriver so I had to use needle nose pliers..is there a tool I don't know about. Tonight I am going to put some EL34's in it..can't help it I am a tweaker. Mcinku where do you have your OD pot adjusted to, and which side do you read it from to know where say 10:00 is, this may seem like a stupid question but I have to ask. I am pretty sure I got it right just checking. I did not get the gain I wanted, but like I said I did not have a lot of time to play with.
Also have you change that resistor by the trimmer, just trying to get a feel for what makes it be all it can be.
It is definitely a good amp.
So far I didn't touch the amp (except bias thing), I did my homework, so I know what to do, if I want to change something... but before I do that, I must learn what this amp can really do. This is my first D style amp, so there is a learning curve I guess. ...and also, I'm building a combo cab. Until I have this done, it's not smart to mod anything. This cab with the G12-65 will create a certain sound and I'll go from there.
I've learned one thing though,... this is the best amp I ever played and I'm so happy about that.
