I grabbed a couple of NOS Sylvania 6V6G's from an antique store last weekend.
5 bux each.
They tested good on the Hickok 6000A, (3450/3500).
I'm wondering if the old 6V6's would be safe to try out in the 5E3 Tweed Deluxe?
I tried each of them in my single ended lead-it only runs 360VDC on the plates. Sounded good and didn't run too hot.
I Don't recall exactly where I ended up
voltage-wise on the 5E3, but it is stock.
What say ye?
Plug 'em in and see if they melt?
