SV83S monos on ebay
08/19/13 at 22:13:23
 
Hello,
I am back from the wilderness Grin About 5 years ago I sold 2 Zen triodes (run mono) for a pair of Wavelength Gemini monos. I have never quite got over it. The Wavelengths are fine amps but they are not my beloved Zens. Today I recieved the SV83S monos I purchased on ebay. These are beautiful but I have some concerns. I am not sure they are original monoblocks. They look like but have 2 sets of speaker posts on each one. Were they made this way from Decware? After viewing pics on the site I dont see these models with that many binding posts. It has no owners manual and I am not sure how to hook the up to the speakers (one red/black on each side or on the same side). Another dumb question - can you power up a tube amp without speakers attached? Any help would be appreciated.
Thanks,Greg

Thanks, yes I need to get some pics up. Just have to figure out how. The tag on the bottom says they were built in June of 2010 by L. Di-Aping,serial #'s 099 and 100. I have looked for the owners manual here with no luck.They look the part, switch in front,3 output tubes, very well built. The 4 speaker posts on each one seem wrong and I am not sure which 2 posts to hook up to. Could be an old wives tale but I have heard to never power up a tube amp that is not connected to a load.

It would be hard to blow up a transformer with only 4 watts, which I believe that those monos are. You could connect them without speakers briefly.

You had best contact DECWARE about these. It is basically a discontinued product - the one with the mirrored top plate and three output tubes. They would know all about its use.

On the EL34 Monoblocks I had from Steve both sets of binder posts were useable, and only one had to be "connected." I'd be surprised if this were not the same way. . . .

I asked that because I read it in the owners manual for the Zen 2 channel here. I dont remember doing that for my previous Zeen 2 cahannel amps.
Thanks,
Greg

Wow! Those look great!

And the quality of the wiring looks like Decware work.

Anyone know what those little blue pill shaped resistors are? I'm not familiar with that brand.

Well they are operational....not sure what I think Undecided. I have them running in the single output tube mode. Everything is very bright and harsh, what is the typical breakin sound like? These are supposed to be brand new never used.
Thanks,
Greg
