Re: Bogen CHB50--first project?

Yeah, it's a great deal. Can anyone tell me if those transformers will work in some sort of 2x6L6 Fender build?

What specifications would I need to know to determine this?

Re: Bogen CHB50--first project?

Another question for you guys about the Bogen CHB 50--looks like it's still for sale and the price dropped to $30. He said he turned it on and the tubes lit up--looks like it might be worth it just for the tubes at this point. Anyway, I've been reading up--I got Dave Hunter's book and read that, and...

Re: Bogen CHB50--first project?

Hmm... what about this Filmosound amplifier? http://detroit.craigslist.org/okl/msg/3481971043.html

A kit would be nice; I'm just seeing if I can save a little money...

Re: Cordovox amp

OK, so just a power amp. I'll pass on this one.

Cordovox amp

I found this on craigslist: http://detroit.craigslist.org/okl/msg/3484120317.html

Looks like it's an accordion or combo organ amp... anyone know anything about it/what model it is? How would it sound as a guitar amp?

Re: Bogen CHB50--first project?

Learning a little electronics is unavoidable in this hobby. You need to at least know how to read a schematic, identify componants, trace the signal path through the amplifier and have an understanding of lead dress, but any level of understanding brings more possiblitites. The Dave Funk book is a ...

Re: Bogen CHB50--first project?

Sweet! Thanks guys. I talked to the guy on the phone; he's going to test it and let me know if it works. From the prices I've seen, it looks like I'll do well if I can get it for $50 or less. What if it doesn't work? Is this amp pretty simple to diagnose, and would it still be worth it? Also, I have...

Bogen CHB50--first project?

I found a Bogen CHB50 PA amplifier on craigslist (asking $60, I can probably talk him down a little). Is this simple enough to be a first project? I have no experience working on amps (other than a little work on my Hammond/Leslie), and a little electronics knowledge. I'd probably just use it unmodi...

Re: vvr on my Blackstar

The Newer London Power boards do not suffer the lag, I have used them in channel switching applications from no scale to scale mode, although I have not scaled the whole amp in this application, only the power tubes. I also used a voltage clamp on the PI and Pre to maintain a constant voltage and t...

Re: vvr on my Blackstar

The Hall VVR does not "instantly" change volume, FYI, because of the reservoir caps. When I twist my VVR knob quickly, the volume changes level much more slowly, over two to three seconds as the filter caps charge or discharge. Good to know! Have you any idea if the London Power unit behaves simila...

Re: vvr on my Blackstar

Thanks guys. I have thought about putting a volume pedal in the loop, but I normally have the clean channel cranked (perfect volume for my situation) and I'd like to keep that compressed sound (just on the brink of distortion since I swapped the preamp tube for a 12AT7) when I have to play softer. I...

vvr on my Blackstar

Hello all, new member here (a different Andrew than the other Andrew asking about a vvr); I just found out about the Hall vvr and this forum seemed to have the most discussion/knowledgeable people. I'm considering installing a vvr in my Blackstar HT-5. (I know this forum is mostly about custom amps,...
