    Chauncey Epperson has them for $3.95 last I heard at the FM-3 zone.

    Hi Denny:
    I finally had a chance to look at your board schematic. With all the switch possibilities available I think you have it dialed in. You can do the alignment exactly as described in the manual.
    I like it so much I want to try one. How much are the boards or should I say do you have a set of the boards I could buy?
    I have a tuner that is still partially unassembled I can play with.
    It was going to be a test bed to compare with the one piece motherboard tuner I have.
    You should send this idea to Chauncey Epperson who designed the one piece motherboard it would be the final "piece de la resistance" for that unit. It still uses an add on wire and the external switches system.
    This would be an elegant way to eliminate that and further simplify the alignment procedure. Although you still have to remove the top to do it, it is not that inconvenient. Keep your ideas coming. You have a good take on these tuners.

    Thanks, Im currently out of boards but will probably put in an order this week some time. The boards run $175.00 for 4 boards w/ silkscreen and solder mask, and $126.00 for 4 without. You still have plated through-holes,and traces.
