Hi Turnip.
That scopey wopey not a Rigol is it?  I keep looking at the Rigol DS2102..... thought I'd ask, hope you don't mind.

I acquired a box full of valves, all too good  clod out, stacks of 6DJ8/ECC88 and IG3GT/IB3GT HV half wave reccy, good x-ray generators them but not as good as the PD500 shunt stabilizer triodes in them Flipips G6 chassis, hey am showing mi age here.

Goodness me, back on air! Only two weeks down. I wonder how many of us will not come back?
Scopes, 35 years ago, I started fixing CTVs (had a G6 and a 2000) and also scopes. I made a contact at Telequipment who used to buy end of line spares, and he was giving up repairs to take over a guest house with new wife, so I bought all his stuff. That lot set me up, so I concentrated on TQ stuff (and Grundig on TV front). I had to learn a bit of electronics sharpish, but managed enough to do the biz. I packed up both when I moved here 25 years ago, but after one year, I had to go back to Staffs to look after my unsold cottage. So I did a bit more repair for a while. I bought about 15 decent TQ scopes to recon, calibrate and sell, but then sold my cottage (took 7 years), so came back here with the scopes. Because I needed to take a paid job, they sat there, and it is only since retirement that I have fixed them and sold a few. I still have two of those TQs, plus about 6 or 7 others acquired "as you do". Problem is that even after full overhaul and calibration, they are not worth much more than I paid, so no profit. I recently bought a Tek 475A, and use my long owned mains/bat HP1703 tube storage model. Have thought about one of those little chinky things, but somehow prefer something with 10 to 20KV flowing around inside. Full report please.
When I returned to UK in 1990, I took a job sorting out a kiln manufacturer's insoluble problems. Once all done, I was "released", so was stuck, quite penniless. Managed to get a job repairing CDs, which I had never toughed before, so more quick learning. I even became quite good at it, and wrote an occasional column in the monthly. I found that I used my scope most of the time, switching it on as soon as I got to my bench in a morning, so I am quite handy with them. I have an intermittant ignition fault on the 'bike right now, but am going to diagnose it with the scope, rather than just changing bits, a practice which led my up the garden path a few years ago, when I finally found ALL my spare four coils were intermittantly faulty!
Davy, those ECC88s are probably worth putting on Ebay. I am hoping that with a photo of the CT71 screen, yielding emission and Gm, I ought to get a decent price, especially if I match them. We shall see.
Les.

Hi Dave,

Sorry about the delay - Scope says its a MIN digital storage scope Model DS0201 and seems to do quite a lot for the money, and when time and need permits I will try drive it.

My original idea was to use it to knock up a tester/driver for Vestel backlight transformers. But as it seems they are always duff on those old IPS boards, and mostly unavailable - bit of a waste of time.

Mind you, our 'Old Les' would probably rewind his with 80 SWG DSC Litz wire - Chris.
