any buzzing in the audio, especially with the volume turned down, is most definitely a capacitor issue. at the very least you will need a schematic for the set, or the ability to locate the audio section on the PCB, determine the values for the caps, buy some new ones from mouser and replace them.

just in case anyone is interested this is the design for an AV mod for the famicom. it is rather simple and even reuses the video transistor from the famicom. if anyone is interested i will post a schematic.

well this set uses 'compactrons' almost exclusively, they made much more than would ever be used so they are readily available on the secondhand market, which is good for me because nearly every tube in this set was bad. finding a working vacuum tube tester is another matter altogether. this is what a hand wired chassis looks like.

I just repaired a TV that belonged to this guys gramma, it's a '68 zenith. pretty bitchin' set. it's completely vacuum tube except for one single transistor in the video amplifier.

it's what they call "vertical collapse"

>>1236885
a thin horizontal raster is caused by a failure in vertical deflection. not a serious repair but totally not worth it unless the set has sentimental value.

I was always partial to centipede, giana sisters also.

go for the famicom, all the way. the built in controllers are rather short but whats stopping you from getting a hudson joycard? plus you can get the disk system and play all those great floppy games.

good luck finding a flyback, they only need replacement in specific situations anyhow. arcing, cracks etc. speaker replacement would be rather straightforward. everything else requires many many hours of labor. you're looking ~60 capacitors on average to do a recap. all with specific tolerance. it's really a case by case matter. working on a CRT is not for amateurs, there is lethal voltage even withthe power removed.

hello friend.

>>1236784
and here's a shot of some Strider.

>>1236773
here's what it looks like while doing convergence.

>>1236770
here's some pics of the last CRT I fixed, complete recap, new flyback, new HOT, tube swap. the works.

I left a comment on your video. I professionally repair CRT's, mostly for arcade applications nowadays. let me know if you need any help.

check out the back, so many inputs. I rigged up a SCART cable to hook up my neo geo with RGB.

>>1192817
yes
>>1192818
it's a sony pvm-2530 with some studio monitors

>>1192781
I've been getting heavy into famicom stuff lately, some of those carts are surprisingly hard to track down.

>>1192775
this is my motivation to go on living in this fucked up world

>>1192753
so what's the story?

>>1100894
I did the mod myself, I also put those sanwa buttons in my controller.

>>1100675
here's some south park

>>1099337
it is rather hard to take a good picture with my crappy camera, here is the best I could do.

>>1099037
here's a shot of the chassis, it's all tube except one transistor in the video circuit. notice the color coded convergence adjustments in the delta formation, and the 12 convergence adjustments on the panel in the upper right. if anyone has any questions on doing their own convergence adjustments I would be glad to help.

this set is all factory original, a real tribute to american manufacturing ability and engineering know-how.
