You Can Do This! Open radios without damaging them; Remove printed circuit boards; Identify the electrolytic capacitors in the radio; Remove the old components by desoldering them; Replace the capacitors by soldering them in the correct; locations while observing their polarity; Test and then reassemble the radio.

As someone else mentioned, tubes don't deteriorate from simply sitting around, although capacitors do. If the tubes were OK then, they are just as good today. Some radio circuits are pretty forgiving, too.

Paper capacitors would be replaced by polyester or polypropylene capacitors, just make sure the voltage rating is adequate. New capacitors will have different preferred values from the old ones. Just chose the nearest one unless it is in a tuned circuit. You should not need to replace ceramics or mica caps.

You don't need advanced electronics knowledge to fix most old radios. Tube-powered radios are simple in comparison to modern electronics. Most were built to conventional designs and they use replacement parts that are still readily available.

Older radios tend to fetch somewhat more than newer ones, but only in a very general way. Age alone doesn't make a radio priceless. 1920s radios are old, but some manufacturers made cheap, junky radios in those days, as in all other times. Scarcity of parts can make certain vintage sets very expensive to repair.

As with all repairs carried out here, London Sound provides free estimates for the service, overhaul and repairs on even the oldest of valve radios and radiograms, and also provides a full 12 month guarantee, in writing.

Even though they're ancient by today's standards, these old tube radios can almost always be brought back to life, and there's still plenty of broadcasts out there for them to receive! Not to mention, they just look so classy and have a presence few modern electronics can match.

Mica capacitors rarely fail, but occasionally you'll find a bad one. The following diagram explains how to decode the common "six dot" scheme used in many micas.
