Talked to Rotel Service about the FP/FN1016's in the RB-991

It sounds like the previous owner had the FP/FN1016's put as a non-equivalent device as Andrew from Rotel has never heard of these devices in the RB991!

What a bonehead move on the previous owner!

SO I have some (slightly used) 10 FN1016's & 10 FP1016's for sale really cheap!

$20 for the lot !!!!!!!!!!!!!!!!

Schematic diagram for RB-991 shows what follows:

1. Predrivers: 2SC2910/2SA1208
2. Drivers: 2SD1047/2SB817
3. Output 5 x 2SC3856/2SA1492


That's the only correct situation in Rotel RB-991 and RB-1080. I saw several opened amps and always the above devices are incorporated.

However, in lower models (such are: RB-971/RB-1050, RA-971/-1060/-1062), the output section "stops" at 2SD1047/B817, and for the bigger models, they serves as drivers for all models exept RB-1090 (they use 200w devices)

As for the Motorolla/On semi's, I know someon who had replaced the original OT with Toshiba 2SC5200/A1943, so it should work also with those OT
