For those with a nostalgic bent, I’ll be purchasing transmitters, receivers and amplifiers by Hammerlund, Swan and Drake. Sorry, no Drake L-4B amplifier. There’s a Collins 30 L-1 but the last one I sold went for $700 so it’s a little pricey. If you happen to have an interest please contact me offline or call me at 830-896-9593. Gale KM4DR
