The latest project here is this basket case Tek Type 561B. If I didn't get it REAL cheap I would have passed it by. It came with Type 3A72 Vertical plug-in and Type 2B67 Time Base plug-in.
Front panel. It's all there just needs a good cleaning and sticker residue removed.
Handle missing. I have leather strapping plus leather tools. Used them to successfully make new handles for a Type 535A. Both cabinet halfs are banged up and scratched. Will hammer out the dents and repaint.
A look inside. It's complete but absolutely filthy. Before any testing will give it a complete dry clean.
Front view of the plug-in's. Not too bad but inside tells a different story. Tube raiders struck. Both plug-in's stripped of all their tubes. I knew this when I went to look at it and decided to go forward anyway. The Type 3A72 has a B/W of only 650Khz. Pathetic. So I'll go out on Ebay for a better Vertical plug-in. The Type 2B67 Time Base plug-in is a decent unit but it would cost hundred's to re-tube it. So I'll also look for another Time Base plug-in.
So once cleaned up next step is to check the filter caps for shorts. The Type 561B mainframe is actually pretty simple compared to other Tek's. It's basically a power supply, HV supply, and CRT. The vertical and time base circuits are all in the plug-in's. So I'm going to concentrate on getting the mainframe complete before investing in plug-in's.
I'll update this thread as I make progress.
