My 6AV5GA SET Amp (SOLD)
« on: 15 Mar 2009, 01:35 am »
It was a fun project but.. simple problem. It just isn't loud enough for my 88dB dorm speakers. Other than that, it's completely hum and buzz free. On my 98dB speakers at home, I couldn't even tell the thing was on. Black background.

I designed and built this in my workshop in Boston. I've built a few amps before and all have been well received. Point to point wiring, teflon jacket interconnects, good grounding techniques.

More importantly, the sound is pretty sweet! The 6AV5GA triode-wired is incredibly linear, and for those of you who didn't know, was actually re-badged by tube factories and sold as a 6B4G replacement.  Surprising amounts of bass from the very derated Edcor output transformers. Smooth treble. Coupled with some nice, efficient speakers, this amp will definitely not disappoint. 









Asking $350. Located in Ithaca, New York but willing to consider shipping.

Nice looking amp.  What do you estimate the output to be?  Also, how many inputs does it have?  Finally, what are the dimensions and weight?  Thanks for any additional information.

Thanks! Output ought to be around 3.5W per channel. The tube I'm using has very similar curves to a 2A3. I can scan the triode curves I used, someone on a forum (forget where) plotted some points and derived their own. Just one pair of RCA inputs. The chassis is a 12x8x2" aluminum one with vent holes on the bottom, with two wood panels on either side that are .75" thick, 2.5" tall, and 8.375" long. Total dimensions of the amp are about 13.5" wide by 9.5" deep (binding posts and volume pot stick out) by 6.5" tall. I haven't weighed the thing yet but I estimate it to be about 20-25lbs, maybe a bit more. Needless to say, this thing is going to take some careful packing.

At the moment, it's being prepared for shipping to Hawaii :o , but if things don't work, I'll let you guys know. I'm going to miss her.
