Anyone need a microcontroller chip for their Golden Tube Audio SI50?

Bought this unit (GTA SI50 MKII) with entire control system (bias LEDs, input select, power LEDs, Remote Volume Control, etc) not functioning - so I bypassed it, and worked great.....well that as a few years ago...

Finally got back to the real fix - that known microcontroller issue - anyway, found the hex file at Yahoo Groups and programmed a new - blank PIC16C72-04/SP chip, and now front panel control all working again...anyway, I burned three, only needed one (these are write once - OTP - microcontroller chips, and I anticipated problems...bah). Let me know if you need one...the chip cost me $4 from digikey...

This is for the SI50 MKII, not the SI50 MKI (the MKI controller hex file is also on the Yahoo site)...
