Yes Tektronix makes some nice boards. Given those white ceramic spark arrestors on your board it definitely would appear to be from an oscilloscope. Tektronix was always touted as the best manufacturer of scopes although I always thought they had too many bells and whistles and were just too complicated to set up for simple bench work in my view. For computer repair work it was usually most important just to see if a signal existed, not to check the precise timing and waveform shape. If I was designing though then maybe.

Also HP and Agilent boards from various test instruments often have gold traces. I originally used to go through the hassle of peeling the traces off the boards before I learned better here. With the HP boards though there were definitely at least two levels of quality. On some HP boards the gold traces peeled off totally pristine while on other HP boards (apparently with thinner plating) the gold would crumble and turn to fine dust as the traces were peeled back.

Actually, the real value in your board is from Tektronix equipment restorers. Your board has 4 tunnel diodes (the little gold plated diodes like the one directly above the "PC" in the far right of the top photo. Those easily go for 10 bucks or more each if they are good (HINT: Don't go checking with an ohmeter, cuz they go poof inside and are no longer useable.)

If you have a quantity of Tek boards, look to eBay to get your riches from them. There's a Yahoo! group (TekScopes2) where you can flush out any value as well. If you need more info, send me a PM (private message).
