I bought a Sprague T03 from eBay and it arrived today. It seems to be in fair condition. The front panel is in great shape. The case is dirty but no scratches or dents. Just lots of dirt on the original crinkle-finish paint. The leather carry strap is in really bad shape but 50 year old untreated leather isn't very durable. So I opened it up and the insides look very good but it will need some work. New caps. I found a pair of 25 uF electrolytics and four 1 uF electgrolytics that need replacing. Also found a couple of .02 bypass caps that are the old wax coated caps that need replacing. I also found a 250 ohm, 5 watt resister that I am suspicious of just due to its age. It's not burnt or anything but being that old I just don't trust it. It only has a power supply tube and the magic eye tube and both can still be found for sale as NOS. Soon as I round up the replacement caps and resistor, I'll give her the smoke test. Wish I had a variac transformer. I'll let you know how it goes.
