why GU74-B It is tetrode, you will need screen grid supply etc.
You can use 3CPX800, I got a pair medical eq. pull for 350 US$ from eBay, just
plug in and still give more 1500 W output. It need more driving power but it is
ok (grid current 30 mA.plate current 1000 mA for 1500 W output).

Subject: [Amps] Tentec Titan 425 with GU74-B????
I'm looking at buying a pair of GU74-B's to have on hand as spares for my Titan
425. Has anyone out there replaced the 3cx800A7's with GU74-B's??
