The schematics from the Eico HF60 and Unipower LW-958-A are'almost' identical, except for the output transformers. One of the unipower amps has the power supply section modified, ie. They replaced it with a solid state rectifier etc.. These are'integrated amplifiers' meaning they have a pre-amp circuit built in.
I will include copies of the manuals for both the Eico and Unipower amps. I have not powered them up. Please ask if you need tubes as I might have some. I hope someone can get these working!
