It hadn’t been used in decades and has sat in a closet for all these years. It had a massive (maybe 50′) 4-wire cord with an appliance plug on the end. We cut most of the cord off as it was simply too long. You’ll probably want to install a new 3-wire cord. We also noticed that the meter switch is frozen. This will have to be repaired or replaced before the amp can be used. The amp hasn’t been tested in any way, and the tubes have been removed for use in another project. If you prefer one carrier over the other, please make that request when paying for the item. Rest assured, you’ll receive your item in excellent condition!

This is a nice Drake L7 amplifier. It’s in fair cosmetic condition and from a smoke-free home, but certainly isn’t going to win any beauty contests. One knob is missing the metal inlay. Also, the aluminum trim has some sort of brown residue on it. It’s on there pretty good but may come off with the right chemical. Aside from that, it’s the small scuffs/scratches you’d expect from equipment this old. I would note that the power supply is pretty dirty/dusty inside and would benefit from being blown out with an air compressor. The amp itself is clean inside. It’s currently wired for 120VAC and has two Eimac tubes installed. We see no sign of modification and all components appear original. The amplifier runs well. For CW, plate voltage sits at 2100VDC with no load. Keyed-down with 60 watts, we got 600 watts out. For SSB, plate voltage sits at 3000VDC with no load. Ensure this amp will meet your needs, and just as important, be sure you’re comfortable operating it. I’ll say it one more time…. Read the manual before purchasing and operating the amplifier. I can take the tubes out if you like, but I would personally recommend leaving them in. They are tight in the socket and are not going to come out. But, as I said, it’s your call and I’ll do whatever you prefer. Lastly, Please note that the plate meter isn’t operational. Also, I would encourage you to replace the power supply’s capacitors before putting the amplifier into service. It wouldn’t be a bad idea to give the RF deck a going-though as well and replacing some of it’s components. As I mentioned above, all components look original and probably 40 years old. If you expect 40 year old capacitors to hold up well for much longer, you’re going to be disappointed sooner than later. If you need to hire someone to do this for you, I can get you in touch with a qualified technician. If you prefer one carrier over the other, please make that request when paying for the item.

This is a very nice Heathkit SB-221 amplifier. As you know, the SB-221 covers 80-15 meters (no 10 meters, sorry) and features quality construction. This particular amp is in great condition. It does have a switch added to the front panel to toggle between “standby” and “operate”. I don’t know who did the modification and the reason for the octal sockets under the chassis, but it looks to be very well done. The switch matches the originals, and the workmanship in is evident. This was certainly no amateur hack-job. The amp also features a matched pair of Eimac 3-500Z tubes. On 40 meters (SSB) with 60 watts of drive, we measured over 1100 watts PEP. On CW keyed-down, we were getting 700+ watts out. The amp’s technical specs call for 2KW input on SSB and 1KW for CW, so this amp is running great! Please realize that this is a vintage piece of equipment, and unless specifically noted above, it has not been fully restored with new components. It will inevitably need maintenance, however it’s impossible to know whether that will be next week or a few years down the road. Unless you are capable of doing this work yourself (or have access to someone who can), we suggest you revisit the idea of whether this is the right equipment for you. This item will be packaged using our InstaPak foam-in-bag system, ensuring the utmost protection! Bags filled with a chemical mixture expand around your item and harden to form a protective, yet forgiving, foam barrier. IMPORTANT: You will only receive what is photographed. If it is not shown in the photos, it is not included in the sale. This includes items such as original packaging, accessories, manuals, and so on. Speaking of manuals, it is strongly recommended that you thoroughly read it before attempting to operate the equipment. If a manual is not included in this sale, you should download one.

These tubes were removed from an amplifier we’re parting out.

This amp is in pretty good cosmetic condition. There are some scratches on the cabinet, but the faceplate looks great. It’s very clean inside, as you can hopefully see in the photos. Now, for the bad news. It was working fine and was putting out full power, or as close as we can with an amp that’s wired for 120VAC. It wasn’t until we brought it over to the photo booth that the I noticed the band switch felt a little funny. After playing with it for a few seconds, it completely gave out. I opened the amp up and found that the switch had completely broken in half (see photos). It’s a good amp, but obviously it cannot be used until the band switch has been replaced.

This is a nice amplifier. It has some scratches on the cabinet but looks good overall, particularly the faceplate with really looks great. Also included in the sale is a reproduction of the manual. With a line voltage of 230VAC, the plate voltage sat at 1850VDC in CW position. With 45 watts keyed-down on 40 meters we measured 500 watts out, which is about right as the manual calls for 1000W PEP and we can assume 50-60% efficiency. The tubes are getting extremely hot (orange in color) when we put the amp into high-voltage position. The L-4B was originally designed to only work with Drake equipment. This one has since been modified to work with other transceivers, and we used an IC-706MKIIG when testing rather than Drake equipment. Perhaps this won’t happen when using Drake gear? Bias current may need to be adjusted. There may be something else going on that we aren’t aware of. This item will be packaged using our InstaPak foam-in-bag system, ensuring the utmost protection!
