@8th-note Not surprising what logistical problems you would have with repair or resale at the old monster Krell level. Given your good fortune with repair, sounds like a lifetime amp and good investment decades ago.
I will definitely advise buyers this is original condition, no caps replaced as yet.
Just bought a 45-lb Coda that checks my boxes, so at my age fuure equipment repair/upgrade should be easily manageable. (Well, except for a monster dual-firing Tannoy sub that I won't keep and needs the new amp plate installed before resale . . .)
