Supratek Tubes and Tube Swappin' for Everybody
Just for completeness, I'm running a Mullard GZ33 rectifier, and single triode 2C22 linestage tubes with the VA 350B. The VA took about 10 hours to mellow out - there was a little bit of brightness at first, but that smoothed out nicely. 
Supratek Tubes and Tube Swappin' for Everybody
Just reviving this old thread as I have found what for me is the best regulator tube I have heard in my Supratek Chenin, that being the Valve Art 350B. I know there have been posts from others extolling the virtues of the WE 350B but that is SUPER... 
If you have a line conditioner, does noise matter?
I have a PS Audio Power Plant Premier, a DIY parallel AC filter, RC filters inside my preamp and EQ, snubber caps on all tube heaters, ferrites on the heater and B+ lines, and my preamp uses DC for the signal tube heaters. Every single additional ... 
Infinity RS 2.5 speaker placement
Hey Sswanny,If you are in the central NJ area I'd be glad to demo them for you. You could hear the new Apogee diaphragms in action, and maybe get some ideas for your 2.5s. 
Infinity RS 2.5 speaker placement
They fit right into the stock clamshell. The only difference is that they have a wire flying lead instead of the solid tabs to accomodate all the different EMIM shells out there with different lead spacing.AK closed the thread because they wanted ...

That's EMIT, not EMITY! 
Infinity RS 2.5 speaker placement
He doesn't make EMITY diaphragms, yet...Here is a link to the Apogee forum - Graz is the owner, and he is taking pre-orders for his next production run. His first run of 60 sold out.http://www.apogeeacoustics.com/forum/viewtopic.php?f=15&t=187... 
Infinity RS 2.5 speaker placement
I own RSIIb's as my main speakers. They have more drivers than the 2.5's so take this with a grain of salt, but I find that a slight toe-in works best - I cross the tweeters a couple feet behind my listening position.If you intend to keep them you... 
Capacitor log Mundorf Silver in Oil
There are a lot of manufacturers, I've used MG Chemicals and GC Electronics epoxies in the past. I'd go with a clear epoxy to avoid any possible ill effects from the filling pigments. I don't see an issue with putting a tube in the center to reduc...

Irish, you can buy potting epoxy in bulk for bigger jobs at a somewhat lower price per unit volume. I've seen up to 16 gallon containers from MG chemicals. It's not really cheap, but it's a lot cheaper than new Duelund or Northcreek 8 gauge induct... 
What Benefits Do You Really Get?
Class D amps can be left on permanently. My Gilmore Raptor monos do not even HAVE an on/off power switch, only a mute button. The manual says to leave them on 24/7 for best sound.

A cheap experiment might be to just pot the stock inductors in some type of ABS container using epoxy potting compound. That will eliminate the noise from vibrating loosely-wound coils and give some of the effect of a CAST-type inductor while keep...

Check out Solen Heptalitz inductors. I use them on the parts of my RSIIb crossovers that handle above 1000Hz, where their higher Q versus solid wire inductors comes into play. They sound spectacular for high mids and treble. They also have somewha... 
Tube Preamp with adjustable gain
Supratek preamps also have adjustable gain. 
good cable for internal speaker wiring
By the way, all wires were tinned then directly soldered to the drivers. Pairs of wires (+/- for each driver) were twisted together to reduce RFI pickup - the wires for the three tweeters were then bundled into one Techflex tubing bundle, as were ...
