|A heartbreaking sight...|
|Courage old chap! You'll make it!!|
It was in rather heartbreaking conditions, all broken up, its nice bakelite casing in pieces (with some of them and the back cover missing) and everything covered up in years and years worth of grime and crud. (Click on the pictures for a larger version). One of the keys in front was missing, the power tranformer was burnt up, an IF can had a bad winding and - the worst - ALL of the RF coil pigtails at the underchassis were cut, probably by an industrious rodent which had left clear "marks" of its presence in several spots. Several other electrical problems became apparent during the restoration work, but they were not so serious.
|RATS! Where are the coil pigtails?|
|Keeping detailed notes is a must.|
After ordering and installing a suitable new tranformer, I gradually checked and restored each stage. Surpisingly, most of the capacitors were OK! If memory serves, I found only a couple that had developed leakage. The reservoir electrolytic had more than its nominal capacitance and normal ESR.
|Starting to look like a radio again...|
To make a long story short, after restoring the function of every stage, I fully realigned the radio and it gradually came to life. First I aligned the IF, then the RF stages. Getting the dial indications to precisely correspond to the actual frequency is a very rewarding procedure. Stations started pouring in when I attached a wire antenna, and all of the wavebands became operational.

|Finished and singing!|
The Marconiphone radio restoration is another epic story, soon to be told!
