All 4 tubes were tested on my calibrated Mercury 2000 tube tester. The tube has 4800 micromhos at 100% power according to factory specifications. Each of these tubes has well over 5000 micromhos when measured. Each tube was tested on all parameters on close as well as gas, all fine. Not to be compared with inferior Russian tubes, which do not reach these performance values when new. Also no amplifier modification as with 6CZ5 replacement tubes necessary. I think stronger 6973 power amp tubes will be hard to find. Only with good tubes the amps will sound good again. shipping worldwide This part ist located in germany but I can ship this one worldwide. I have enough experiences with international shipping. Please contact me for your personal shipping quote. Please have a look at my ebay feedback! Thanks for watching!

Pair 1950s vintage SEEBURG HFA4-56 Tube Audio Hi-fi Amplifier PP 6L6GC RCA Era. For parts or repair. Your getting TWO. Please take a good look at the photos. One unit is missing the fuse cover. The Ac cords are worn at entrance to the unit. One has an extra piece with it. The base of these measure 14” x 7” x 8”. The control knobs turn as they should. I will pack both together in one shipment and pack well for you

Offered for your consideration is a vintage UTAH OE specification number 512655-3 12 inch Alnico magnet woofer, USA-manufactured in 1965. As I’m sure you know, UTAH was a leading supplier to the domestic speaker industry from the early 1960’s through the late 70’s in addition to making their own speakers.Based on the EIA source/date code on the mounting flange, 328532, this woofer was made by UTAH (328) in the 32nd week of 1965. It was removed from a large SEEBURG DWS2 speaker.So, please have a look at my large photos and read the remaining description to decide if this outstanding UTAH Alnico woofer should be yours. This UTAH woofer is in clean, excellent condition. The sturdy, deep set paper cone is structurally perfect with only some discoloration at center—caused by being mounted behind a protective crossbar on the baffle—and the voice coil dustcap is flawless, as pictured. Plus, the fabric-roll accordion-style surround is permanent textile instead of the fragile foam that was widely used in that era. Also, the steel basket is finished in attractive blue enamel, including the huge bell covering the magnet’s keeper, and its in great shape with no dings, scratches, or rust. And, the negative +/- terminal appears to be SEEBURG-specific female, but can be snipped-down to leave a standard male spade. Overall, this vintage woofer is exceptionally well preserved. Most importantly, it’s been fully tested and sounds very strong with clear, detailed lower midrange, solid low end, and the warm vintage tone that keeps Alnico drivers in such high demand with those that know. And, I tested its DC resistance at 4.7?, consistent with a nominal 8 ohm driver rating. Lastly, the basket measures 12¼” diameter, it stands 6½” tall, and the four mounting holes are spaced 8¼” adjacent (skipping a hole) / 11¾” on the diagonal apart, c-t-c.As pictured and described, this splendid UTAH 12” Alnico magnet woofer is offered at a competitive price. Terms of sale:I encourage interested parties to ask any questions they may have about this listing before committing to purchase. Payment is due at checkout by PayPal or other accepted methods. This is a heavy driver, so U.S. mailing addresses will pay $29.95 for very securely packed shipping via FedEx or UPS with tracking, delivery confirmation, and insurance.AK, HI, PR, APO & U.S. Territories must pay additional charges for U.S. Postal Service Priority Air Mail (even though checkout might still show FedEx Ground, a service not offered to those destinations for obvious reasons). International purchases accepted only from those who are able to pay with PayPal, including shipping by insured U.S Postal Service Global Priority Air Mail—fast but expensive—no exceptions. Thanks for looking! *The woofer will have a piece of sturdy cardboard secured over the cone with wire ties at the four mounting holes. Then it’ll be wrapped with a protective sheet and placed in a sturdy box with shock-absorbent materials. This will ensure the cone, surround, and terminals are fully protected, and that there are no disappointments! *the photo directly above is presented only for donor model reference
