It is in very good cosmetic and electrical condition. I hesitate to say "mint" or "like new" because it's over 60 years old. This is not an estate radio that has been sitting in storage. I have had it for 5 years and it has been in regular use. During that time I have replaced the 6BA6 tubes with NOS. The “can” capacitor has been replaced with a Hayseed Hamfest replacement. - It covers 540 kHz to 31 MHz in 6 bands and has calibrated Band Spread for 80, 40, 20, 15, and 10 meters. The Product Detector allows reception of CW and SSB while still having the AGC and S Meter functioning. A 60 kHz IF provides switched selectivity appropriate for AM, SSB, and CW. It has Hammarlund's great sounding tube audio...I am listening to it as I type this. - An original Hammarlund HQ-180 Manual and HQ-180A Supplement are included. - Asking $475 plus packing/shipping (pick-up preferred). (Delivery at Hamvention may be possible.) - 73 Paul, N9PL Listing #1767094 - Submitted on 05/05/26 by Callsign N9PL, Modified on 05/07/26 - IP: syn-045-037-211-083.res.spectrum.com Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend  MISC - F/S GIANT 4 INCH NIXIE TUBE   I have available for sale one Burroughs B-7971 NIXIE.
