Looking For Service Manual for Rotel RB990BX

dtm1962 · 9th March 2008, 07:42 AM

Looking for the service for this unit. It is different from the RB991 as the 991 unit has 5 Sanken (1492/3586?) pairs per channel and the 990BX has 6 pairs of Toshiba output devices (817/1047)

Any help would be appreciated.

Thanks in advance,

The schematic shows the Sanken 1492/3856 outputs and only 5 pairs per channel with 817/1047 drivers.

You know what..... I didn't pay attention to see if there are all 817's or maybe the first one (on the heatsink) was the 817/1047 driver and the rest are 1492/3856?

Please send me the schematic if you possess it.

Thanks in advance

Yup I'd say you definitely didn't pay attention

Contact: Techsupport@Rotel.com

They send out all technical manuals for free via email in .PDFs.

You will have it in a couple of hours usually!

Good luck!

I was wondering if Rotel still supplies service manuals via pdf for free?

If so they are a very forward looking company as most just turn you away to commercial sources!

Thanks,

Rotel will send service manual in pdf, all they ask is your serial number on back of the amp, I have 991, sorry no 990.
