About to start on something rather unique and interesting...

Its late here and I should gone have to bed ages ago but just had to post an update... I traced the no video fault one of those horrible solar filter can 10+10uf caps, one side has gone shorted that supplies HT to the video amp tube. Temporarily put in a new 10uf 400v cap in place and now we have a picture!

It was quite an historical moment to finally see a picture on it after 24 years!

The horizontal hold/sync is very touchy so there's still more work ahead but hey good progress already. I'm quite chuffed to be honest.
This will spur me on to continue the revamp of the electronics. Can't wait to get rid of all those Solar caps.

Earlier today I had a window of spare time while our son had his afternoon nap and went down and started testing all the tubes and I found that every 6SA7 tested bad.... I confirmed this again with my AVO Mk4 VCM and all of them had very low anode current and very low ma/v indicating they were past it.

Luckily I have a stash of NOS Kenrad 6SA7's, these also came from Alan's estate so I installed a total of seven new 6SA7's in the set. I made a point of checking the new tubes and they were spot on as to be expected.
But just so weird how all of them were low?The weak tubes are all Tung-Sol.

I've included a couple of photos of the cap replacement so far, I have a bunch of NOS Japanese .1uf 630 volt polyesters which I'm using, they are perfect for the job and don't look too out of place either.

So that's pretty much it for now, I guess the work has only really started...now the fun begins!

Enjoy the photos

Cheers
