Here is a screen shot. The contrast is anemic, so I set the bias down so the pic doesn't wash out. The chassis will be pulled tomorrow and all controls and the tuners will be thouroughly cleaned. I'll check tubes and clean any questionable tube sockets. From the looks and sound, and the fact that I was able to achieve good vertical linearity, I don't think I'll need to replace any caps. I have more details on my website.
