Roberts R505 - No VHF/FM
« on: April 25, 2017,13:16:40 »
Hi folks,

Got one in for repair and needing a 9v centre negative PS as Roberts are awkward.

AM is fine but not a squeak from FM. Note it uses a Mullard LP1402/2 module incorporating tuning cap for AM and FM and a couple of grounded base transistors for the VHF side.

Any ideas ? - Chris
