This is new developed PCBs for audio transformer. One for upgrading old transformers to use over 15W and also new protection boards for treble panels. Both PCBs fit in existing screw-holes.

First sample of real handmade spiderleggs with same shape as orginal sides. Absolutely stunning quality. Just bolt on. Adjust listening vertical angle with center back-leg screw. Sins they are higher than orginal they are little less tilted but fully adjustable with back leg screw. Can be completely vertical and also fully tilted.
I have an fine carpenter by my close related. And we have a nice cooperation about this.

These looks gorgeous! I have only legs made out of mdf sheets cut out, but painted to match the overall theme of the speaker.

Did some work with EHT units yesterday. Melted wax and new diodes inserted.

I am skeptical that the power supply caps would make any difference due to the long time constant for charging the panels. But I'm willing to entertain that idea vs on the 63's where there is an air-gap between the HV supply and the panels.

Agree with you Sheldon. I dont think it will do any difference sins if you unpower the panels they play with full power for a while...
 
I have done some more job on a friends ESLs. They do really perform well now. Not needed to open the cells this time.
