I tried to to post this to the FB group Vintage Transistor Radios, but the FB app crashed and I lost several lines of my typing. Makes me angry! The radio was not making any sound. I removed the chassis from the case. I found the ‘battery saver’ slide switch had been forced apart. I

From FB group Vintage Transistor Radios My comment about a radio for AU$5400 on eBay. Dreaming, or more like wishing and hoping for a sucker to buy it. But at least he had enough sense to add ‘or best offer’. If someone offers a hundred, maybe he’ll take it. I’ve had a few successes with

I was the only bidder on a lot of three radios, one of them is an Olympic model 860 AM transistor radio. This radio uses four AA cells for a total of 6 volts DC. Overall the radio is in good condition – no chips or cracks. I powered it up and if I turned

From FB group Electronics Hobbyists, regarding the Zenith Royal 500 radios. Clyde Hendrickson There are two 50 uF, 10V electrolytic capacitors under the battery holder. Replace them with 47 uF, 10 or 16 volts. There is also a smaller capacitor next to the other, it might be a 3 uF, or a 16 uF, 10V.

From FB group Vintage Transistor Radios I’ve considered converting a tube set to transistors. The problem is getting tube bases that aren’t sharp and breakable glass. Some old electronics used tube base type plugs for relays and plug-in modules. Then there is the problem of dealing with the higher voltage. Transistors can handle 300V, but

From FB group Vintage Transistor Radios For the last few months, ever since I started experimenting with oscillators on the AM broadcast band, my attitude towards auxiliary audio inputs has changed. Earlier I thought that it would be convenient to have an aux input. But I was leery of making changes to the collectibles radio

For FB group Vintage Transistor Radios Speaking of fuzzy garbled audio… I won another auction for a Zenith “Royal 510” which I’d never heard of. It turned out to be a Royal 250. The seller got no bids at all, so with less than a minute left I bid the minimum ten dollars. I got

From FB group Vintage Transistor Radios I’m flabbergasted. I received the Zenith Royal 755 I won last week – auction link is below. the seller said repair/parts, but I’m amazed at how good a shape it’s in! I suspect that it was in storage for most of its life. The leather case is nearly new,

I got another Zenith Royal 500 at auction, I think it was $20 but the shipping cost a lot. I got it out and tried it out. I found the battery contacts were in good condition. The battery compartment was missing the cover. It came with a leather case, so that will stop the batteries
