Philco 96
#1

Hi Guys,
I have a question about fuses. I would like to place a fuse holder in the chassis of the 96 and was wondering what size fuse and do you prefer standard or slow-blow? Is there a general rule for fuses for all transformer type radios? Thanks much. Bob

Hello Bob, I also fuse many of my vintage radios. I have found that most of the time, a 1-amp fuse is sufficient to operate all my radios after a complete "re-capping" of my radios that have a AC power transformer. I dont fuse any of my ac/dc radios, but use a "safety cap" where applicable on a "live" chassis design.Determining the "surge factor" involved on initial power-up of different types of vintage radios with a AC power transformer will also have a factor in determining the proper amperage of fuse you should use, and if they should be fast or slow blow types used in your model 96 circuitry. I have found that most fully-electronically-restored vintage radio chassis usually draws only about anywhere from 3-tenths to 4-tenths of 1-amp if everything under the chassis is operating correctly. I use the fast-blow type myself because fuses are alot less expensive than replacing any transformers! I will add that I am not familiar with the model 96 chassis, but offering info that I have found always works for me. I have over 100 fully restored vintage radios in my collection, and 1-amp fast-blows are installed in the ones with a ac pwr transformer with no operating problems at all. Randal

Thanks much Randal. I do agree better safe than sorry. This model 96 chassis was only half way done by someone in the past. He rebuilt some blocks but left others alone. I will complete the work now. Thanks again, Bob
