New Traynor YBA 100!!

Do you mean the 15 210 single cab Traynor makes?
I'm running one of these:

And loving it.

Others do the modular version of

and

The two configurations sound very similar to my ears. The 1510 is somewhat lighter than the two cab combination, however, it does have to be moved in one go rather than two trips.
 
Question maybe for @GrapeBass or anyone else who may know.

Would it be advisable if I swapped a 12AT7 or something else in place of the 12AX7 in the preamp to get more clean headroom before the preamp distorts? Right now I am using the -6db input, but thought using a lower output preamp tube might give me more clean headroom before going into distortion. Also which tube would I replace? Looking left to right, there are two tubes behind the Gain knob and one in back of the Master knob. Can you please tell me, going left to right what each preamp tube controls?

I like the way I start to get drive just after noon on the gain knob, but this would be useful information none the less.

If you haven't tried this already, you may want to try turning the master all the way up and use the gain to set volume levels. That should give you the most clean volume possible with the stock setup and then, if you want it, crank the gain some more and get power tube distortion.

Thanks, I have tried that. I have read the entire thread. I was just looking at it from a different perspective. I have a high output passive bass that when I dig in it seems to be too much for the circuit and I was wondering if an AT7 would tame it some. BTW I am loving the warm creamy tones I can get from this amp.

the input gain should be turned down to suit.

Do you need to dig in for more volume or you like the sound of overdrive?

You said the old bug word ''headroom'' prefaced with the common lie ''clean''.

Headroom is unused volume but commonly we mean to say ''additional volume''.

So what I think you meant was you want the amp to be louder before it distorts. The only cure for that is a bigger amp.

See CheezewhizMcNuggets' epic thread on his Ampeg 100w preamp tube swap. Same-same--different maker.

Remind me on Monday to ask the designer.
 
Anyone found an cover for the YBA100 at a reasonable price?

Otherwise my options are to do some exacting measurements and have one made or take my chances with sewing my fingers together.
I’m having one made by Tuki covers. The price was as much as a Gator bag but is sized to the amp. Should be here in about 10 days. I’ll post a report when it arrives.

My question was what I meant to ask. The amp lacks headroom, this is why I asked if a lower output preamp tube might give it more clean headroom. I think we can agree the amp definitely has its limitations, part of why I had it up for sale. It definitely hits a wall digging in on the lower notes. I understand what is happening. No offense, but not everyone who asks a question on this board is a neophyte.
