This may be old news, but I'm searching for an answer: I have a Wadia 850 that needs service, and several calls to their office have gone unreturned. The website (http://www.wadia.com) is active, but that doesn't necessarily mean that the company is alive. I know that it went bankrupt once before. Does anybody know if the company is still alive? If not, does anyone have any ideas of who might be able to provide service? Thanks very much.

hello,

this is probably a completly assinine question, but here it goes. i just bought some event 20/20 v2 passive moniter speakers, and when i hooked them up to my reciever and gave a listen they worked fine until i turned the volume up on my reciever (it was set to very low) and as soon as i did, my reciever flashed "overload" a few times then shut itself off.

I know very little about tubes. My question is about tube rolling. In general, are older NOS tubes able to handle higher plate voltage than most modern tubes? In setting the idle bias with only a multimeter and bias pots, assuming that the answer to my first question is yes, is there any general rule of thumb on say 6BQ5/EL84 Telefunkens, Mullards, RCA and the like?

Good Day All.
