I just got my RP25 yesterday from ebay, It was a spares or repairs special. On arrival No Sound!!!. A quick touch with a screwdriver showed that the audio was working, tapping produced sound temporarily on FM. This was tracked town the ext I/P skt. There is no AM though.!! Taking out the chassis etc showed that (It had been got at) all the AF117s had been changed to BC214LBs,!!! Some had the bases connected to the screen connection??? Voltages on the devices were completely wrong, desoldering and checking the 214s showed that they were connected wrongly anyway. Substituting BCY70s for the 214s in the IF stage produced some noise but the Voltages were not all OK, there was a broken track!! changing the LO tr to MPS5815 and repairing yet another track brought sound at last. Now I JUST have to realign it!!!!!!!!!!!!!!!!!!!!!!!!!!!
