So I believe I had this amp,bought it in the late 70's, used it till it went out in the late 80's. I thought I remembered it rated at 50 wps and also having a start up breaker that took like 5 seconds till it would click and let sound on. I didn't see that with yours here. Great video and thanks.
I have the 6500 which I have been using for about 6 months or so and now plan on refreshing - caps etc., so this should be an interesting watch. Thx for video!
I was told those sleeves you find on power resistors are intumescent and supposed to stop open flaming in the event of failure. Could be a fun experiment to see if they work.
Too bad they didn't include high pass filtering. Maybe the next models do. Well, replacing the fuse as I am sure you know Trevor that doesn't negate the issue with why. 😂 See these caps...you know what I 'm thinking.... So, Trevor I'm going to assume you'll rectify the bare wire wrapped with tape etc. You, may, as we aren't at the end yet but to err on the side of caution I'd replace the drive transistors.
I don't believe that the blown meter lamps that you pulled out were original; they were covered with green Mylar sleeving that would typically be on AKAI lamps (and on a few other makes but not Pioneer). It gives a nice subtle green glow. I wish that I could find a source for purchasing some stock but I've never been able to find it.
Long road to hoe on this one Trevor hope my SA 6800 with the Blue vacuum lighting, I like it, very simple design, does not have any issues like this. Agree with how power transistors connect to the board, using a torch on those new power transistors, high risk, I know it is the only way, why not de-solder the old Bat wings?. However surprised the Diodes failed (Check Va. of Electronic flow). Words cannot express how I hate idiots that do 1/2 ass lighting. Original lighting mounted to VU Meters, WHY? Did not look like Fun, do like the reflect the light philosophy. WTH, cut the Yellow jumper. 50W output, not bad since rated at 45W
