Traynor YBA300

The YBA-200 is running 4 6550 or KT88 though. I think the reason it lacks headroom is mostly because it's under trannied. That's how they can make it so light. It's light even considering it has toroidal trannies.

Given the same tubes installed the YBA-200 should get as clean and loud as a Hiwatt DR201, right? Don't think that's going to happen.

I think the difference in headroom between 8 and 12 EL34 would be marginal in this case. (Heck, the VB2 can get 300w out of SIX EL34, if you use the right tubes and drive them really hard).

The difference between 8 and 12 6L6 is probably much more noticeable, is my guess.


EDIT: Not only tried, but own the YBA-200

I'm a bit of a tube newbie so you'll have to excuse my ignorance... Why would the difference be different between 8 and 12 6L6? Would it be a difference in volume?

Thanks!

I'm sure the VB2 can get 300w, but cranked like that ain;t what I mean by "clean headroom". You have a point about the transformer though. We'll just have to see how the YBA300 sounds! I'm pretty sure they used the number and tubes they did for a reason...
 
Nothing not real about toroidals. They do the same except better, less noise etc. I've used a few valve amps with toroidals and a hell of a lot with Partridges, the ones with toroidals tend to have fiddlier preamps due to the modern, which is much more to do with the tone than the output transformer.

Thanks for that. I don't know the reasons behind what I heard. I like toriods in my SS heads - lighter, no hum, and a better package size. Win win win.
 
I also owned the YBA200, and like others have expressed for years, the clean sound at high volumes was what was most lacking. Otherwise it was great! The user serviceability on this amp and the expanded headroom are the key features that have my attention.
