Get this one for much less. The 807 is a readily available tube that flies somewhat under the SET radar - and is well worth exploring the sonic virtues of. Take a look at the photos - the amp is in very nice condition. The below is from an ad for the amp by Mr. Had: " *After all these years of designing and manufacturing audio amplifiers, on a few rare occasions an amplifier presentation of the music will bring tears to my eyes. This, "Sweet-807" amplifier, as I have named it, is one of those emotionally charged music presentations with tears of joy as the reward of this new design. I recently was reintroduced to the 807 tube by an audiophile buddy here in Raleigh. He asked the question .... "What do you know about the 807 tube for audio?" With that I had a flash back and off I went on a mission of 807 tube designing ... just to see how this tube would sound as a single-ended class A audio amplifier. I am truly excited about using the world famous 807 vacuum tube that went into one of my first "home-brew" novice ham radio transmitters as a kid back in 1958. Well, now I know why this tube is world famous. Truly amazing great hi-fi home audio sound for sure. No matter the choice of music you enjoy or the playback equipment you use, this new "Sweet-807" will reward the listener with the emotional impact and realism of the original score. On a technical basis this 807 music machine has a number of features listed below: * Fully regulated low impedance 807 tube screen grid B+ power supply
* Fully regulated low impedance input tube driver, 6922, B+ power supply

* 9 watts per channel output w 274B (5U4) rectifier tube or 10 watts per channel output with 5AR4/GZ34 rectifier
* 6CG7 additional input tube included for some tube rolling fun ... the 6CG7 is the equivalent of a 6SN7 in a 9 pin package * * I guess you can tell I am excited with the "Sweet-807" stereo amplifier offering. I hand build each amplifier from the raw metal and basket of parts. I consider this my form of musical and electronic art. Each amp is a new baby to me and I listen to each amplifier in both the shop listening room and my home listening room. This is a passion I have held for over 55 years now ever since I listened to my neighbors McIntosh vacuum tube hi-fi amplifiers. I never dreamed that retirement was going to be so much fun!!!!!!! Love it!!!!! * * Dennis J. Had - retired Founder and President of Cary Audio Design * * The tubes included with the "Sweet-807" ... NOS RCA Black Plate 807 output tubes, 274B rectifier tube and a 6CG7 input tube rolled in place of a 6922 * * I received these output tubes a few weeks ago and they are amazing .... amazing lower register slam and midrange bloom. This amp is nothing but fun fun fun .... Love it!!!! Speaking of 807 vacuum tubes .... search EBay "807 Tube" .... over 400 offering ... this tube is nothing but audio fun in the Inspire Sweet 807. * * The reviews are coming in at a steady pace .... The Sweet 807 has truly become a very serious high performance stereo amplifier ...... folks love their Inspire Sweet 807's ....join the fun!!!!! Dennis *"
