Jfrech, recabling of the intrachassic IC requires only basic soldering skills. I used a three-twist of Audio Consulting 24awg silver wire in natural cotton sleeves-- about $50 per chassis. You can use any good IC that isn't too thick to route down center between the PCBs. You would also benefit by hardwiring the master/slave connection that converts stereo to monoblock. Free free to email if you want more info. I'm in the NE. There's a sleeping giant in there...
Tung-Sol Reissue 6SN7 vs EH 6SN7 - Differences
I ordered a matched pair of the new Tung-Sol 6SN7GTB tubes being made in Russia for my Supratek Chenin preamp and have been listening to them versus the stock 6SN7EH tubes. The Tung-Sols sound a bit fuller in tone than the EH, while retaining the bass and treble extension of the EH - in short, I prefer the Tung-Sols.
Before listening, I examined the two tubes very closely side-by-side, and could not see any differences in construction other than the fact that the Tung-Sol has a black plate and the EH has a gray plate. I was expecting them to sound identical, but I noticed the fuller tone of the Tung-Sol right away. I decided to contact New Sensor and ask them what the difference between these tubes really was.
They answered my email within an hour or so, as follows:
"The Tung-Sol 6SN7 has internal differences. The internal geometry is different and the grids are gold plated."
If we take them at their word, the Tung-Sols are not merely re-badged EHs as has been suggested by some. Thoughts? Anyone else have the same listening impressions as me?
