Not my first rodeo but thanks for your concern. Yeah. Ebay is where it came from seems like most non working radios come from fleabay and are described as working. Once you receive them, they dont work. Seller then blames the shipper. I have over 300 radios here a lot came from ebay but the...
No schematic but I think that these were badged under multiple names. The tuning can slugs are painted in place and removing them is a real chore. The threads often strip when trying to soften the paint. I triedcto slign the output and wound up with the sliding slug issue i fixed that with a...
My superbase is dead. Nothing but static, no tx, no rx. I havent started on itbyet but did do some research over at grumpy's. I readcthat the superbase was notorious for leaking caps and the goo eating runs on the board. I did notice a crystal with 3 leads. Never seen one before. Does anyone...

I was able to get most of the radio transmitter working but still have some issues with the transmit. Im getting a 2w carrier on AM and 4W peak. Pretty sure that I should have a better carrier on AM than 2 watts. On SSB, I get 2 watts full whistle on both USB and LSB. The7558 is new and works...
