I should have asked for advice before now but here goes.
I started a mic build with a FLEA 47 body I bought a few years ago. I had them ship it with a “FLEA Next” bell which has a Binder connector. I had an AMI BV8R transformer to use. I started off with the idea of using double 6028 tubes but later changed my mind and decided on the EF800. These are the problems I ran into and how i dealt with them, perhaps wrongly so. I welcome advice and comments.
Wiring. I started with 22 awg teflon insulated wire but found the wire bundle would not pass through the hole in the transformer deck. Not wanting enlarge the hole and risk damage, I left the ground wire at 22 awg and used 26 awg for the rest. The 26 wire was pvc insulation. Bad?
When I wired the connector, I used Max’s MK-U47 build as a guide, pins 1,2 audio pins 3,4 and 6 to ground pin 5 105v.on my 7 pin Binder. When I changed my mind about tubes, I used pin 7 for the heater with 22 awg wire. Strange configuration?
I am concerned that i used pvc insulated wire in the high impedance section. Should I start over and use teflon wire throughout? Should I rewire the connector to be more like Dan’s D-EF47?
Should I/can I clean the acrylic high impedance deck (for lack of a better word)? Will alcohol damage the part?
Thanks for any advice.
