I have been offered a 21EAP4 CRT to replace my dead one. Seller claims it tests at 90%. He wants $100. It would probably cost me $60 to $70 for packing/shipping.

Is that a fair price?.

I was thinking maybe I should stay away from one of these because of their high failure rate. Do I have a real concern here?, and would I be better off finding a 6v replacement?

I already paid too much for my Philco Barberpole set, so this just adds to the hurt...

Thanks for all your wisdom.
