PHILCO 90 - 47
#6

Translation:

Thank you very much,
As of today I have finished the restoration of the Philco 90 (valve version 47).
I have changed all the capacitors. Empty the old one and put a new one inside the Bakelite capsule. In the same way I performed the emptying of metal capacitors 24 and 30 and replacing current capacitors. In the same way I have proceeded with the two electrolytics. If it were not for two resistances that I had to change for being out of tolerance, the restoration would not be noticed. The cables are all original except for one.
In short, it has been very good.
This morning I made some tests and they have been completely satisfactory. Various stations are heard with extraordinary power.
Actually the Philco 90 is a great radio!
I already want to find another model and proceed with its restoration .....
Greetings to all.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
