This Lafayette KT-340 Communications Receiver is electrically the same as the
HA-230. It was in a terrible state when I bought it. However, after many hour's work, it's taken pride of place in my workshop.

Frequency coverage 0.5kHz to 30mHz

Circa 1960s

Lafayette Service Manual HERE

I'm a radio amateur and I love tuning around the short wave bands. When this Lafayette came my way, I decided to use it in the workshop for listening to short wave broadcast stations. Here are a few of the many repairs I carried out... Replace both dial drive cords, two valves, and mains lead. Completely realign IF and all RF stages. Replace several capacitors and burnt up resistors... And the list goes on.
