The Tympanium is a proven, American-made unit to replace the rectifier and zener diode of just about any vintage British machine.  Comes with wiring diagram and installation notes shown.  Coupled with a capacitor, the battery can also be eliminated.

I will answer questions promptly, good luck and thanks for looking.

Buyers please note:  If you're buying multiple items (and lots of folks do), then when you're finished, please either 'Request Total from Seller' (me) or just wait for an invoice.  Ebay's shipping calculator is terrible and I ALWAYS combine shipping when possible for the cheapest cost to you.

Thanks for the help.

Joe
