Smoke!! caused by a capacitor

Submitted by hapoe on Thu, 2012-10-25 16:10.

Got a B77 from a friend. switched it on. Nothing....until smoke emerged.
I found a burnt black remains of an unknown thing.
With the scematic it appeared to be the 0.1 mu in the supplyline.

It's playing now. Thanks to the great schematics.
Wonderful that you HIFIengine people make that valuable info available

HS Variation, and English user manual?

Submitted by Neil Wilkes on Sun, 2011-09-18 18:39.

In the manuals I cannot see the English Language user manual.
The service manual is superb - wonderful and many thanks - but I would really welcome the user manual too.

Also, is there much difference between the MkII and the HS variation, or is it the same?

Revox B77 MKXX PP99MKXX

Submitted by robydragon on Mon, 2010-05-10 05:58.

Many thanks for the people that took part of the time to upload the manuals, very nice stuff, recently I owned a PR99 MKII and with the info of the B77 MKII server and PR99 MKIII server I can take full maintenance of my mint condition unit. Thanks a lot again and it will be very helpful if someone has the service manual of the STUDER A807 open reel recorder and Revox B215 and B215S cassette decks service manuals, and information of the STUDER A721 cassette deck. It would be very nice to get that stuff too because I´m seareching for those units I mentioned. THX!!!! Roberto.
