Re: Help 'tuning' Trapshoot wallhanger receiver board (1975)

Will do!

I see you are in Canada, so I will get a money order for the $80 (it may
take me a couple of days for the MO).

I am sending it to John's Jukes Ltd. 2343 Main St., Vancouver, BC, Canada
V5T 3C9.

If that's not okay, please let me know ASAP.

Thanks John!
