1963 Murphy B801 7 Transistor - UK Vintage Radio Repair and Restoration Discussion Forum

Hello

An yet another success, although this radio has been in testing for a while, I actually acquired it some time ago. I will keep this brief as details on its dismantling can be found on my earlier restoration of the almost identical Bush TR114 a few months back.

This Murphy B801 is absolutely mint, not even a light scratch on it and was probably only used once, if even that, before being stuck away inside someones cupboard for 40 odd years. Even so, it didn't work at all

The problem as usual was AF117 transistors, two of them in this one had failed. I had a stock of NOS AF116s, around 50% of which were faulty, so Ron Bryan very kindly discharged a cap through a pile of them, between the screen wire and the other three soldered together and I decided to use a couple of these in this set to replace the dead AF117s and to see how they performed.

So two AF117s were duly replaced with these AF116s around three weeks ago and I have been using the radio from time to time and I am very pleased to say that they are working well and the radio works perfectly

No problems at all

Its good to have a mint radio now and then, apart from the above all I had to do with it was give it a 10 minute clean and polish

This one too has now joined my favorite radios on my welsh dresser.
