Hello Again  Tom and WW-Crew,

KL has compiled a list of definitions on his Website.  That wonky
cable must be replaced. I have an orig. UK style alum. connector
plug  avail. Email me privately.

RE:  Essential PM list for Trons, You basically have to give the Tron(s),
the "once-over" , leaving nothing to chance. That headblock cable for one.

I generally start with the motor.  Is it noisy ? Is it secure?  Belt OK ?
Is it holding speed ? What control board is fitted ?   That sorta thing....

Then I proceed to the audio.   Heads OK ? Cable OK ? All Ctrl. Pnl pots clean,
not scratching ?  Head azimuth OK ? Any hum/buzz or etc. from output ?

The power-pack is next.   Caps OK or old?  Wiring mods to spec?
(i.e: for SMS or quieter audio )  Semiconductors doing their jobs ?
Steady DC from supplies? No AC components on them ?

Then comes the  "fun" part .  Tapes knackered or good ?  Adjustments
to pads/rollers?  Felt secure on same ? Pads/Rollers aligned, and rollers
free to turn ? Edges chamfered for elim. of tape migration ?
Return springs OK on rack ?  Guides/combs clean and not bent/distorted ?

This is typical checklist, Tom.  Functionality only, not even cosmetic stuff.
For cycling models, the  To-Do List is tripled in size.  Hope this helps,  JK
