any experience with audio valve?

If you can get them at a great price, DO IT!

I have the ppp45's (no longer in production), which are the little brothers (50 wpc) to the Avalon (75 wpc) (still made). The ppp45's sound amazing; the Avalons are bigger, more powerful, and include cool LED's next to each tube that tells you when a given tube needs to be replaced. They are auto-biasing and require almost no maintenance. Don't quote me on this but the Avalons may also include balanced inputs.

Don't hesitate; these are outstanding amps that unfortunately don't get as much publicity as many other amps.

thanks for the info.

I can't say much for the distributor of AV, but the company owner and designers of the products are first class all the way and extremely supportive and courteous. All you need do is email the designer and his wife will respond to offer any help possible. I have both the Eklipse and Challengers and am super happy with the products. I also found good buys and am holding on to these well built monsters. I have owned Aragon, Coda, Audible Illusions, Kora and Clayton Audio.......these are keepers.....build quality is first rate.
The sound is some of the best I've heard......

I have unresolved issues with the AV auto bias system in the Challengers.
The lack of near by service facilities should be a consideration one should note before purchase.
The manufacturer will NOT provide you with a schematic so you can have them repaired by competent local vacuum tube specialists like Alan Kimmel or Tom Tutay on the East coast.
You have to ship these to the west coast and take a chance on real shipping damage. These beasts are large and heavy and are very difficult to ship safely.

I was offered the choice to remove my circuit boards myself and send them to Germany. Not an option for the technically uninformed.....
