12ax7 Preamp Tube Help - Specifically Type 7058
PostPosted:Tue Nov 17, 2009 12:58 pm
Hey folks,
I got a great deal on my absolute favorite preamp tubes, NOS RCA 12AX7. The guy I bought them from also sent me an NOS RCA 7058. Can I use this in my guitar amp. Reading up on the tube, this concerns me:
"Same as 12AX7 except for a 13.5 volt non-tapped filament. These can be used in circuits which don't use the 6.3V filament tap. Performance should be identical to any equivalent 12AX7."
I really don't want to mess my amp up and I have limited eletronics expertise.
Peace,
Gil
