The model 228 was a 200-watt tuner, with SWR meter and sliding coil contact,
much smaller. I think you meant to say 238, which is later version of 229, as
others have mentioned.
I once bought a used 4229 kit version, which didn’t work. Sent to Ten Tec
repair, they said builder had wired switch backwards.
