Urgent question about tube testers.

[benman94]

I have two options available to me, and I need to make a decision quickly. I can either purchase a Hickok AC-51 in beautiful shape that costs only $90, or I can purchase a Hickok 800K in rough shape (possibly quite screwed up) for $210. Which is the better deal? I know there is more data out there for the 800K (really just a re-named 600A), but I can't imagine that building an adapter for 9 and 7 pin mini-tubes would be that hard. Tube data (and settings) could easily be created for the AC-51 using manufacturer spec sheets for each tube. Any thoughts on this would be greatly appreciated. Need some guidance here . . .
