Default Looking For Service Manual for Rotel RB990BX

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.

Default Maybe I wrong when viewing the Heat-Sink mounted devices?!?!

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

email address is dmullins@cogeco.ca

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,

Mitch
