Hi everyone, New here. I inherited my grandfathers Bounty Hunter RED BARON VLF SPD. No other models numbers shown, so believe it is an RB7 type - yes vintage I am after schematics for this unit please. Did some searching but did not find. After reading some posts, it seems this unit suffers from someone plugging in power incorrectly. It has 2 x ("9V" battery type) connectors. I believe total power for device is 24V broken into 2 x 12V packs (8x 1.5V AA batts per pack). These carriers have been lost. There is a blown transistor on the Blue PCB ( PCB code PCB26 PNI) Cannot see transistor type- too much damage. Most images I have seen of these RB7 have a beige PCB where mine is blue.... I repair vintage Hifi for a living, so with schematic can trouble shoot other components I must say the power wiring is "creative" and wanted schematic to double check as well. It seems RED wire from connector A and black wire from connector B are JOINED together on the blue PCB, whilst the Black from connector A and Red from connector B go to the ON/OFF /Volume switch. If anyone could assist with Schematic, you would be my hero. At very least, explain how the 2 x 12V packs are wired- preferably in " sketch" Then will have to find out what type that transistor is somehow. No doubt the IC beside this is probably gone, but at least this still has type on top,. Pics attached Cheers from Australia Danny BH_RB7sheet.pdf
