MC 240 ReTube or Replace

Fire sale is good, I need another to match my 1961.
Heavy gives good advice on swapping tubes.
you might consider having it gone thru by competent tech: Audio Classics, Terry Dewick, Mike Samea in Michigan can do a bang up modification w HK style regulation, Finally Randy Vikan at Elite Audio Tech on Key Penninsula in WA is fantastic.
Tube amps are dominated by sound of the transformer, find a better output than the 240 ???? Doubt it.
best to you

Yup the power section was replaced with the capacitors.My older than dirt back will NOT allow me to lug around a 60 lb amp these days....
There are internal and external fuses which have randomly blown and to do a lot of further testing I'm going to need to get a lot more of each fuse.........
This is causing my pore ole back to complain!

PM me to offload it cheap, and I help you out.
Alternatively it sounds like it could be a capacitor. Any decent tube person will likely be able to sort it out.
It could also be something with the speaker (like an XO cap), which is presenting a difficult load, or oscillation…
You could switch the RHS and LHS channels to ensure it is related to the amplifier channel.And also which the driving source like a CD player with different interconnects into the unit with LHS/RHS swapped.
I am not even 100% certain it is the amplifier. My amp was also bad until I found it was a bad set of interconnects… Not the ones that I had just soldered up, but the 5 year old store bought ones.

Thanks for the suggestion of lifts....I've used them over the years for several motorcycle builds :-)BUT you still have to get the amp onto the lift And THEY DON'T DO STAIRS WELL :-)
