    Sansui 9090 (not DB) only some function lights working

    Many thanks for the participation on this thread. It was exactly what I needed to move forward. Issue fixed. So there was some confusion on my part back a few posts because I said the power was coming in on pin 39 but @kwayde asked if I was sure and said it should be coming in on 41 (that's...

    Sansui 9090 (not DB) only some function lights working

    I tried putting a little extra bend in that contact you mentioned and got continuity through all the functions while the switch was on my desk. But reinstalled I still have the same old issue. I'm afraid to open it up for a 4th time but cleaning is almost all that makes sense at this point. It...

    Sansui 9090 (not DB) only some function lights working

    That was my assessment as well but nothing I clean with seems to be improving the situation. I did reflow all those pins just in case. The voltage isn't making it through the wafer for aux and phono. This is going to sound silly but it's almost like the contact on the front wafer is a little...

    Sansui 9090 (not DB) only some function lights working

    EDIT: FIXED Was wrapping up a quick tuneup which has now become a long drawn out headache. The function lights for only phono and aux do not illuminate. Replaced bulbs with no effect. Checked power, fuses, etc. The 6.5vac power is present at pin 39, and is transferred to the function bulbs for...

    Marantz 2215 - Lost left channel in FM stereo after re-cap

    Did you take note of this capacitor error on the board?

    Pioneer SX-950

    It should be just fine to bump that up slightly from 1/4 to 1/2 watt (service manual specs the original as 1/4 watt). Assuming you don't have the correct one available and really need to replace the old one.

    Sony TA-1150 Build Thread

    it’s been 5 years so my memory is a little fuzzy on this one. I think the outer cap on the tone control is just pressure fit. The inner section probably has a set screw (Allen head?).

    Sony TA-1150 Build Thread

    My notes show I used ksc2690ays and ksa1220ays for replacements (pinout is different!). I do know Sonys seem to be finicky about drivers and outputs. Although this one worked fine I’ve had problems subbing modern transistors with other Sonys since then. You might create a new post and see what...

    Marantz 1120 thoughs

    I actually like my 1120 more than my 1200. Very nice integrated.

    Marantz 1060B Rebuild & Troubleshooting

    Don’t have a list but most everything is kept at stock values. Usually source from Mouser or Digikey depending on who has stock of what I want.

    Anyone put in a mouser order of late?

    Thx. I was looking for 945CGTA, not the CYTA. Settled for the BU version. Only difference is the kinked legs which I prefer. Stupid little thing but whatever. I’ll take what I can get these days. Also stocked up on some 1815 :thumbsup:

    Anyone put in a mouser order of late?

    Ordered $125 (25 lines) from Mouser on Tuesday afternoon about 3pm. Got shipping notification at 6:30pm. Order arrived via FedEx 2 days later. Accurately picked. Only had to sub 2 items when placing my order but did notice stock levels are really low on some Nichicon UPW caps. Interesting to...

    Really weird issue with Kenwood KR-4400

    I’ll let the experts guide you with the troubleshooting, but if any photos/info are needed I just finished rebuilding one of these a few months ago and it’s still on hand. Assuming you have the power board from the manual (x00-1460-10), then dk5 (d5 on the board screenprint) is just under the...

    Main caps for Kenwood 600

    This one claims to be 51mm x 79mm. 75v 19000uf. https://www.mouser.com/ProductDetail/Cornell-Dubilier-CDE/DCMC193U075BB2B?qs=8kBc1%252BPe71dngKYW5N0xFA%3D%3D I didn’t look at the datasheet so you might want to check that for anything that won’t work in your application.

    Kenwood KR-4070 Recap list

    I'm with @HPMguy that learning how to create your own list is the way to go. That said I need some audio karma and I already have the list so it'll save him some time going through the SM. This was generated on a KR-4070 I worked on 2 years ago and in no way guarantees the exact same parts are...

    Kenwood KR-4400 Documented

    While I was working on a basket case KR-4400 I noticed there didn't seem to be much info on the forum about this model. This thread is just meant to document the components I found inside my receiver. There weren't many variations from the service manual other than the main amp board...

    It’s the very next line on that same post. Omron G2RG-2A4-DC24. Looks like it’s still available from Mouser. Probably others as well.

    Kenwood KS4000R

    Appears to be a few discussions on AK over the years about this receiver. https://www.google.com/search?q=kenwood+ks4000r+site:audiokarma.org&rlz=1C9BKJA_enUS728US728&hl=en-US&prmd=smixvn&sa=X&ved=2ahUKEwiOgpOhl5HzAhULbs0KHQZtBbYQrQIoAnoECAoQAw&biw=1024&bih=653&dpr=2 Reading through them looks...

    Sansui AU-101 oddity on D001 double diode

    Well I guess part of the mystery is solved. I found the other half of the dual diode under the board. Opened the bottom panel to start some troubleshooting and found it. Might as well touch up that solder joint while I'm in there. Looks suspect. Maybe they ran out of 10DC-1's that week on...

    Sansui AU-101 oddity on D001 double diode

    That’s interesting. I’ll definitely be posting a thread on what I found in mine that differs from the rest. Lots of differences from your image including no emitter resistors on mine.

    Sansui AU-101 oddity on D001 double diode

    Took in a Sansui AU-101 on trade knowing it has the left channel out and would need restoration. No problem. Comes up on DBT just fine and sure enough left channel not working. I'll address that later. At the moment I'm documenting all the parts I'll need for the restoration (once I fix the...
