    Recapping a Tandberg TR-2080

    A friend asked me to recap his Tandberg and it is quite a different build than the Pioneers, Harman Kardons, and Kenwoods I'm used to. This TR-2080 is supposedly the TOTL receiver from the Norwegian Tandberg. The receiver has pre-outs and main-ins, so it is easy to identify the constant...

    Pioneer Sx-850 amplifier board issues

    Hello, I am having an issue with a Pioneer sx-850. R38 and Q6 on the power amplifier assembly is running very hot. So hot you can't touch either within a couple of seconds of turning on the power to the unit. The radio was playing fine when I smelled smoke and found that VR3 had a burn spot on...

    Marantz 5220 Wow and Flutter?

    Hi all,I recently had my Marantz 5220 fully revised by a specialist tapedeck tech. I will copy a list of the work done below. However, after the revision there is still audible flutter, particularly when recording, and particularly on things like acoustic guitars and mandolins. In fact it's...

    G-9000DB Distorted sound on left channel (Solved)

    I have this receiver for 6 years now and had no issues with it. Last week the left channel started sounding distorted, even on headphones only, which means this is happening prior to the amplifier side of the house. It starts getting distorted after 10-20 seconds. I did notice that without...

    About to Replace the Capacitors on a Technics SA-202 Receiver, Questions About the Tuner Stage

    So, after catching the re-cap bug from doing my Onkyo A-7070 (holy crap, what an improvement!), next on the surgery table is my Technics SA-202. The Technics, though, has a tuner section, and that is where my trepidation begins. I have heard conflicting reports that replacing caps in tuner...

    Sansui solid state 7000 repair, recap, and restore

    A fellow AK'er has a Sansui 7000 that he'd like to repair and restore, so I said "sure! that'll be fun!" After looking a little into the specs, parts and history of this big 70's receiver I found it is a high power cap-coupled design... so *I* had to buy one, too. So, now I've got two units to...

    AR2a capacitor oddity

    Yesterday I re-did the crossovers on a mismatched pair of AR2a's. I was a bit puzzled to find that the older speaker (c.1961) had the normal values I've seen elsewhere for 2a's - a 6uf and a 4uf wax covered cap. However, the newer one (probably c.1966) had a capacitor that was marked as having...
