Schoeps will not repair VMS02ib, VMS52ub, VMS42ub, or VMS32ub pre-amps anymore - they still service the newer VMS 5 u
Schoeps mainly swapped boards on these older pre-amps and have run out of replacement boards - the components on the boards should be mostly repairable though so this doesn't mean that a damaged unit is dead just not repairable by Schoeps
Sonosax won't repair older SX-M1 and M2 units (specifically the Phantom power circuit) - apparently they used a Neumann manufactured board to provide phantom power and have run out of replacements. The Neumann replacement version of this board has been reported to work well as a replacement for units with failed phantom power - note Sonosax does not perform this repair.
As mentoned above Aeta doesn't repair EAA PSP-2s anymore as well
- Schoeps can not repair vintage capsules as well as the have in the past due to lack of parts - including m221a/m221b/m221f/cmt 30 f/ cmmt 30 f series capsules - These capusles may be able to be repaired by vendors such as Peulso in the US but no garantees
- Schoeps has no AC701 tubes available
- Schoeps is very reserved about service on older FET mic repairs such as CMT series and CMMT series body repairs - the electronics are easily repairable but sleaves, connectors (XLR, Tuchel, Sogie, etc) , power xformers, and other custom parts are no longer available
