So I think my Sunn needs to be retubed. It's a late 60's Spectrum I.

From what I understand it has one 12ax7, a 7199 for the phase inverter, 2 EL34s and I think a GZ34 rectifier tube.

This is the first time I will be retubing this head. I think the tubes are original but I cannot be sure.

What would my best bet be for each of the tubes? I want them to be pretty good quality. But I'm not sure what I should put in there.

Thanks!

I've been using Eurotubes.com for years to retube my amps and have never been dissatisfied.

Look around ebay for a NOS 12ax7. Dunno about the PI. SED Winged C El34s.

Sure, if you like limiting yourself to one brand of tubes. Not to mention that they aren't any cheaper than other sites.
