Bogen DB-115?

[radkrisdoc]

Hi everyone!

What do you tube gurus think of this little critter? Any mod possibilities, other than making a power amp only option? What is life after a recap like? Meaning, is the iron any good? I think it should be, but please correct me if I am wrong...

Thanks for your comments, much appreciated

You know that is a mono amp right?
should sound good just need to get a second one for stereo

 

[radkrisdoc]

Yes I know that it is mono. Might have to look around for another one for stereo. Looks interesting for a first tube venture....how rare is this model?

That OPT looks comfortably over-engineered for a pair of EL84s, but it doesn't have screen taps for ultralinear operation. The power amp circuit is interesting -- it has variable damping factor and even a damping indicator lamp! Anybody know how that works?

So is it PP Class AB? I am yet to learn tubes lol but do know my way around SS.

 

[BinaryMike]

It's push-pull, for sure. And it must be class AB, but with 50mA of cathode current per tube, it's not going to spend much time operating outside the class A region. The output tubes probably run rather hot.

Thanks...that makes it even better!

I'm going to bring this thread back from the dead, as I am now in possession of this little amp. Seems very well built, I'll cook it on the variac tomorrow and see what happens.

Anyone got any new info? Only seen 1-2 of these things around the web.

 

[vinyldavid]

Cooked. Motorboats, one 6BQ5 out. Time for caps and a nice new pair of 6BQ5's.

How did your venture go? I am looking at a pair of these and am curious how yours turned out.
