My only present source for 8233/E55Ls is junker 3A1/3A6 P-Is (no extra charge for cath interface laden & defective tubes), is there another reasonable priced source? Last retail price I saw was about the same as a whole surplus working modern scope, ca $85(?!).
I just looked up the price of new 8233's in the 2000 Antique Electronics Supply Catalog and it listed them at $37.20 each. Not as bad as $85 but still more than I want to pay . . .
