I've owned a blackface Super Reverb for years with only about 15 hours use in that time. (My acoustics take up most of my playing hours).
When I got the Super there was a single no-name 15 inch speaker which I've replaced with a 1973 Altec Lansing 12 incher. I put a double 12 baffle in but currently have my second Altec 12 out on loan to a friend.
What are the risks to using it with an 8 ohm load? I have no idea how long the 8 ohm 15 was in there, but I'd bet it wasn't used hard with that speaker.
I run the volume 6 to 8 with the Altec 12. The amp's had no maintenance of any kind in 35 years. I've never changed a tube and it's possible the tubes are all or mostly original. I'm assuming it needs caps and probably some resistors. What kind of cost am I looking at for that work? And what improvements should I expect?
The only obvious issue is a scratchy reverb pot. I have no idea if the trem works as I have no footswitch with it. I definitely don't want to risk damage from a wrong 8 ohm load now that I'm using it again. Thanks for giving me the benefit of all the accumulated wisdom on the site.
