Myles, thank you for your recommendation of Doug Preston at Dougs Tubes .
I just placed an order with him, and I must say, he is a pleasure to deal with. I told him that you recommended him.
On your advice (from a previous post), I'm getting (balanced triode) JAN Philips 12AX7WA and JAN Philips 12AT7WC tubes for my '68 (AB763) Bandmaster.
I also ordered a Sovtek 12AX7LPS (balanced) for the phase inverter on my 410 Hotrod Deville.
When I can afford it, I want to get the JAN Philips 6L6WGB's you mentioned earlier.
I made a mistake (before I went deep on your site) and got a matched pair of Svetlana 6L6GC's from The Tube Store .
They seem to be OK, and assuming that I won at "Russian Roulette" (literally ...Svetlana ...Russian Roulette ...get it??? ...never mind)
In general, what do you think of the Svets??
Thank for all your great info. It is very appreciated.
