[DMcMahon]

Found that I had not screwed on the tape counter pulley far enough down the shaft of the Take Up reel table (at Post 23), had not followed the advice from ricard at Post 17 of holding the pulley and turning the reel table, had just tightned down the pulley until if felt really tight.

The pulley screwing onto the shaft is really tight so this time used a 6mm box spanner (had to spin over the mains transformer for access) on the plastic hex nut that is part of the pulley and held that firm while rotating the bottom section of the reel table until fully screwed down.

Now no springy play in the table and FFD fast winding works very well, sometimes a little squeeking when stopping.

Definately no playback sound on the previous tape tried. Touching the Playback head connections gives loud hum so PB amplifier not dead.

Tried another tape and the left channel played back fine, probably a mono recording. Need to do some test recordings and recheck playback.

Need to re-assemble both the 6021X and 3041X before doing any more testing, have numerous bits everywhere, before I lose some bits or forget where they go. On both units the wooden surround is broken with 1 side panel completely broken off so need to repair those also.
