Thanks to Tony and Dwight for their advice on repairing my ailing teletype model 33 ASR. It is now functioning correctly. The problem turned out to be the trip lever which had come unseated from its guide, plus a mal-adjusted distributor. The distributor clutch was permanently engaged, not synchronized with the keyboard. Characters printed OK when holding REPT because the keyboard reset concided with the start of the distributor cycle, bringing them both into sync while REPT was held down. I should have realized this before as I watched that distributor whiz round and round... D'oh. Anyway now it runs a lot quieter too and the carriage responds crisply to keystrokes after all that cleaning. Dave __________________________________________________ Do you Yahoo!? Yahoo!
