Technics SU-X901 amp

2 faults: left hand channel has lost base tone. Both channels sound has intermittent crackling. Both faults are definitely the amp. I have visually checked for obvious faulty components, e.g. burnt or blown ics, caps etc and have thoroughly dedusted to eliminate tracking. Help needed to source a replacement amp as I feel that the faults are somewhat obscure for usual repair shops.

Thanks ....... Bob.
