Antique Sound Labs AV20 Ideas?
« on: 11 Jul 2015, 01:35 am »
I have a pair of Antique Sound labs AV20 Monos.  They are all original including the boxes.  They are beautiful 20 Watt 6L6 amps that I have had for years, mostly because it just didn't seem worth it to sell them.  A few years ago I put them up for $400 I think, I guess that was too high.  Does anyone want to either make an offer or give me a ballpark price?  I can post pictures later in the weekend.

I'm in Southern California between Riverside and Palm Springs. Zip Code 92223

Thanks,
Jeff Brown

You might want to post a zip code to let members have an idea where you are.

These amps sold for $250 each when new. I'd guess about $300 would be fair. Very simple circuit that lends itself to modding. Please post more details about condition (pictures), hours on tubes and tube cages, if you have them.

Condition:  They are currently stored in their boxes in the attic where they have been for the last several years.  I have the original tubes with the pretty green logo on them, I have no idea how many hours are on them.  I might have a new pair of EH 6L6 tubes in the garage. I'd be happy to throw those in, or take $50 off to offset the cost of buying a set of tubes of your choice.  I bought them new, and they didn't come with cages.

I'll bring them down and fire them up tomorrow, get some pretty pictures to post.  They really are pretty amps, I remember them having a super warm sound.

Make a note of whether or not they hum and also note that they may need re-biasing. The circuit (on AudioKarma) shows them to be manually biased. I think they have 8 ohm taps only, limiting your speaker choices. They are configured as Pentode from the factory but can be changed to UL, if anyone cares.

If they are hum-free someone will get a bargain entry level tube amp  :)

They did hum some,  cheater plugs mostly fixed it. They are very easy to bias with a jewelers screwdriver.
