There are some that have been played with (modified) in the past, and those that cause problems have been restored according to the circuit diagram. Some of them are left as they were. See photo of heater switch on rear panel, etc. As for the reception, the VR, band switch, etc. Had noticeable contact defects, so they were cleaned. A semi-fixed resistor was removed during cleaning, so it was replaced. The crystal in the HET OSC was defective, so it was replaced with a replacement part. The RF amplifier was also replaced, and the S level was increased by about 2. We adjusted each part according to the service manual. Since we do not have satisfactory measuring instruments, the adjustments were made amateurishly. We confirmed that the output power was approximately 100W in CW on all bands. As I said, these are amateurish measurements. Please pay within 3 days. International Buyers – Please Note.
