Hello Jon and everybody,

KL just coined a fantastic phrase ! Screeching-Cable-Rot
occurs with either an intermittent connection at the moulded
headblock plug to the preamp, or faulty 1/4" phone jack
connection on lower-right for foot-pedal.

JB always replaced the moulded plug with nice alum.
equivalent. The actual name for these connectors is
"Belling-Lee" and still used in the UK for UHF television
connections. These are seen in every Mellotron,
and abound in MK1/2 models.

Worst manifestation of "SCR" is reception of radio
signals,which can actually magnetise the heads in left
unchecked. The headblock is a wonderful device to
search for RF, if ever the Arecibo-Dish goes bad,
we can attach  EVERY Mellotron headblock together
for a "Very Large Array" , and listen for prime numbers.

Hope this helps, JS.    --Jerry Korb--
