Yesterday I was playing my new amp for a few hours together with OTS with G12-65... at band volumes

...we all know OTS is one hell of an amp but man, this BM is something else.
Compared to OTS it has less mids... more or different kind of bass... the notes just pop out on BM... sound more clear with better string definition. OTS sounds almost congested in the mids somehow. I know OTS sits well in a band mix, still have to try the BM but I think it will do just fine.
BM HRM is an awesome amp and I think it's going to take away no1 spot from the OTS.   

I was sure I would never find even better amp than OTS... damn.

what else is out there...

 

Well it's about the same... but with 6L6 it will be a little louder.

I have blakeface type knobs and I would say when I reach 7 it will start to break up... with SC guitar.

Yes I'm running 6L6 right now.
To me is sounds a little bigger with more low end... a few more W as well.

Not sure I don't know what is the spec of KT66.... I think you better ask Nik. 

Yes I've seen that, looking good... I wish that faceplate and chassis would  be available when I was buying mine.

Ok I'll say a few things but my opinion might change after I learn more about this amp.

This amp has a lot more bass and it's less middly ... FAT as HELL.
Has less overdrive compared to OTS and the character of it is very different. It sounds like a trumpet with a spongy feel to it.     Sorry can't do better than that. 
It sounds bigger, that's a fact...
That's all for now.

I didn't even play with the HRM yet... I just set everything to 12:00 and played

You're welcome... I enjoyed this very much... I'm almost sorry it ended, not that I mind having a new amp 
I played it yesterday... just a few minutes (didn't have time for anything more) but I can already say this amp is very much different from my Overtone... and I couldn't stop smiling while I was playing.
Can't say much more at this point.

 

Sure thing
 

These are my plate voltages...

V1a   196V
V1b   198V
V2a   193V
V2b   193V
PIa   255V
PIb   247V
6L6   471V

...and finally one happy picture for the end 

We measured around 40W of clean power...

It's alive.   


I took the amp to my amp tech for initial power up...
Here's me setting bias at around 33mV

It took me a little over a week... I usually started to work in the evenings, after kids went to bed...around 3h per day... under 30 hours I would say.

I'll ask my tech if I can borrow his HRM (I hope he still has it)... so I can compare OTS, HRM and BM HRM... all 2x6L6 versions.
I'll try to set up my recording gear and try to capture that... should be very interesting... and useful for everybody considering one of this amps.


 

Glad to know that documenting this was worth while...

 

Hey guys, don't start pushing my buttons... 

 

Don't own one but I did play it... and you're right, it's an awesome amp...but man, I really don't want to think about another amp at this point... I just finish my newborn yesterday and it didn't even cry out yet 

Not bad for my third amp build ever, isn't it...and not to mention my first D style, so I'm quite pleased with the outcome.
I'm taking her to my amp tech tomorrow...we'll power that scope and sine generator and see what this baby can do.

All good things must end at one point.
