Hi
I have a pair of mid s/n (14000s) ESL 63s in need of an overhaul.
Reading the ESL 63 service notes, Quad recommend the use of a specific design of tone burst generator and give an example schematic (Fig 3, page 8).
Before I go away and build this, which will take a couple of hours at least, has anyone got one or knows where I can get one or even if someone has done PCBs for a TBG?
Thanks!
Ps. I am a professional EE with the correct equipment and knowledge, used to working with (very) HV and have a high degree of personal caution/self preservation! Having said that, I've never worked on electrostatic speakers before.

Hi Jan,
See service manual attached. Fig 3, page 8.
Ps. I have and have read every edition of Linear Audio - an early subscriber - and was chatting to Morgan Jones about these speakers at a show only yesterday.
