 RADIOANQ - Drake 2B + 2BQ + xtal calib + extras
Drake 2B with xtal calibrator + 2BQ Q multiplier available as a set only. Have a filter capacitor replacement kit and a spare set of tubes. I have not installed the cap kit and will include it with purchase. When antenna input is shorted and volume turned up all the way, I do not hear any hum. Pickup in southwestern Ohio or will meet you within 100 or so miles of Cincinnati. No return. Will post pix in a few days; this is in B+ condition. The product/diode switch is scratchy, but you probably will not use the diode detector on ssb/cw ham bands. The NL switch is scratchy too but only works with diode (AM) reception. A good cleaning of the slide switches is recommended or replace them. Includes original instruction/service/alignment manual. Email for details. Pix will be posted in a few days. Paypal, Zelle, cash, whatever. The whole kit for $350.
