- Thanks, Byron! I just ordered a few myself - they come with the starting capacitor installed - picture on ebay at item # 1264823433. Should be good for GS-35 PAs since it only requires 88.3 CFM for t

- FYI, y'all! For what it's worth (no pun intended), the GS-23B (4CX1600) can be bought (tested and guaranteed) from "Max", lvs@online.kharkiv.com, for $75 each just now (he apparently has two; not a c

- The 8873, 8874 and 8875 are all 3CX400 tubes. The 8873 is conduction cooled and not made anymore, as I understand it. The 8874 is an air cooled version, with airflow parallel to the axis of the tube.
