Hacker Black Knight RP74MB - UK Vintage Radio Repair and Restoration Discussion Forum

Oldelectronics · 17th Sep 2017, 8:02 am

Hi folks

I recently bought A fairly grubby ( but inexpensive) example of this set I can't though see a service sheet for it? Could I use the Sovereign RP72MB sheet as I believe it's basically the same set but is FM only? Also could anyone suggest the best way to clean the aluminum front without fetching off the lettering?

Kind Regards

Kev

Hi Kev

The RP72 manual also covers the RP74 so should be fine. The black print on these is extremely fragile. I would use hand soap and water with a cotton bud very gently. Do not use foam cleaner as it's great at removing all the print. It does look like someone has used a permanent marker to colour it back in though.

Good luck

Graham
