Very sweet and powerful Berning EA2-150 amplifier.

It was converted by previous owner to use 6KG6A (EL509) instead of the 6FL6 tube. I have 2 spares that will go along with the amp.

It uses 4 6KG6A output tubes and 6 12AT7's.

Speaker impedances of 4, 8 and 16 provided for with 5 way binding posts.

Self biasing. ( I believe it was the first amp to do so)

It has feedback selection switch of 0, 8 or 16 dB. It also has a front toggle switch to limit output to 40 watts instead of 150 watts.

Its the sibling to the Audionics BA-150. Comes with some literature and schematics.

Looks wise, the front is very good, the chasis is strong and tight, the perforated surfaces (top and rear) show age. There is a slight hum coming from the main long black trannie that I tamed by putting some rubber between the trannie and side wall...Trannie mounts might need to be tightened, or the ground?

voltages:
In the instruction manual it says:

117 VAC, 50-60Hz up to 10 Amps
234 VAC, 50-60Hz up to 5 Amps

I think its the little orange wire in the plug that has to be relocated.

Ships from zip 07047, and its a 90 lb package.

Any interesting trades? SET amp?

Selfbias is the best bias system IMO, = long tube life.
This amp is the Z OTL circuit??

Disagree with the self bias comment.  Many designers use fixed bias setups, and the reason generally given is that fixed bias is superior over self bias sonically.

As always, YMMV.

OK. thanks for that info.

Its a c-mos digital logic biasing. It biases the tubes periodically during operation. the logic circuitry constantly measures and adjusts each tube individually.

At start up, there is no sound until the tubes reach a certain temp. and are biased.

Hi,
Seems it is the Self Bias system you are referding to.

yeah, I figured I better read the paperwork and give some info.

Its not a Z OTL...

OK, thanks
