Yes he did I was just poking a little fun. Did do a little work on it but still has the two major problems. Squeals like a pig when you first turn on, it's somewhere in the low level audio after the volume control. And no RF amp on the SW bands only on the BC band. Somewhere in the band switch.
Pete, if you need to find a new home for any of you tabletop sets please shoot me a PM.
Have fun with your new hot rod project!!
