Got the urge to play around with a 1920's TRF set or similar. Found one this weekend at an antique shop in Michigan City, In. It's a "Liberty Five" made by the Liberty Transformer Co., in Chicago. 1925 I think. No tubes or a speaker, but it is in really good condition, just needs some spit polish. Paid $50.00 and I hauled it home (2 and a half hours) in a vacuum cleaner box strapped to the sissy bar of my Harley. The women working there seemed really concerned for my safety ( and sanity). I e-mailed them and told them We made it home in perfect shape. It'll be a project and a learning experience. I felt a nice set of this vintage was almost a must have for my collection. Haven't found a schematic yet.

You know, you can get smaller radios for your Harley.

Always like a set with a lot of knobs to twittle!! Better start save your spare change for buying the 01A's to fill those sockets. And you might want to measure the resistance across the two audio transformers to see if there open, it's a common problem on battery sets.

Hi All;
I really think that You have a Cool Radio, Have Fun gettting it to work.. Like in the Philco Radio Story, You need to get Yourself a Monkey to Tune it, two hands on two of the Tuners and its tail on the third Tuner..
And like stated above You need to save Your Pennies for those 01 Tubes, even though when I looked in the Tube Catalog, I saw You could get used ST types for $20.00 others for $30.00, New for $40.00.. But with five of them that still adds up.. And other Venders may have other prices..
Still best, as has also been stated You need to check all Coils and Transformers.. Keep Everyone posted on Your progress..
THANK YOU marty

The 6vdc "A" battery will draw about 1 1/4 amps but the "B" and "C" will only be milliamps. Try firing it up with batteries first. A stack of 9 volt batteries for the "B" and "C" will work fine and last a very long time. A six volt sealed lead acid for the "A" will light the filaments for hours.
Short pin 01A tubes show up on ebay every so often and you might try a WTB on the forum here. With even one tube you can step through and test each stage with a minimum amount of test equipment.

Well the A supply is pretty easy to build. Just need a good 6.3v @ 3A or so filament transformer, a bridge rectifier, 5000-10000mfd cap@12v and a LM317T IC +a few small resistor and a cap or two. The LM317 is an adjustable regulator that come in two sizes @1.5A and 3A. You can put up to 37v in it and it will regulate it from 1.3v to 37v. If you want to go on the cheap you can use a 5v fixed regulator.
OR You could use the regulator with a 12v car battery to regulate it down to 5V and not have to build a 6v ac supply to start with.
Happy building!!!
