I just discovered you today while I had a discussion about bying a National RX-7200. I was wondering if it was worth it ,sound and all, and mostly how I could have the FM tuner modified for use in Canada if I was going to get it. Superduper mentioned you. So it got me to find this topic. Man, you are a magician!!
Fortunatly found out from the seller that the mod is already done. Hope it is as good work as you have done. But it is still running at 100 volts. Need 120 here also.
If you dont mind, I may contact you in a near future to have that changed. Cant wait to hear that box. Should receive it in about 2 weeks from today. For now I have ordered a 120 to 100 volts convertor. Hopefully it does the work for a while.
