bong, could you please tell me why? It might be helpful for my learning. Thanks!

Here's a brief explanation later in this thread concerning the "balanced" phase inverter fallacy.
The forum there is an excellent place to get high-quality information about tube amp repair and maintenance.

Thanks for the link. Regrettably a lot of it was lost on me, but I'm sure I'll understand in time. I'm just starting to learn the guitar tech stuff. Thanks again.

I;ve never even heard of matched preamp tubes.
Make sure you match your power tubes though.... truth is, you dont need a matched quad, 2 pairs of matched duets are fine if you place them in the proper push/pull configuration.
Did you check my thread about buying tubes cheap? I can get the Svetlana, too.

Ahhh, it was ME that said matched preamp tubes... I of course meant power tubes. Typo.

Paul, I very much wanted to join in on your deal, but I am getting extremely backed up on my projects and as far as I'm concerned my amp is useless right now. I used Steve's link and ordered a matched quad of Electro-Harmonix 6L6GC power's and Electro- Harmonix 12AX7EH pre's. I hope I haven't fucked it up.

This is usually meaningless unless the tubes have been burned in for 24-48 hours before matching, and unless you get your tubes from a relative handful of tube resellers, they won't be.
The import tubes you get from importers and non-specialty importers are very raw, unculled stock and tend to change after a few hours use. The readings you get on a tube will change a little or a lot after they've had decent burnin. This tends to be worst with Russian tubes, in my experience.
Buy from a good reseller - Lord Valve, KCA, Triode, etc. - or pay the price later. Anything less is false economy.
Caveat emptor!

As I already said, premium burn in and matching is $1.00 a tube for most... $3.00 for a select few
Good quality stuff.

Ya I figured, and I appreciate the offer for sure. I've got a LOT LOT LOT of re-tracking to do though, plus other projects.
Hey I found some EMG81 & 85 combo packages on Ebay going for about $130-140. I know your thoughts on the 81, but what do you think about the 85 on the neck?
