Proved that despite its huge size the CD3000 can be shoved down one's throat.

This pair will make happy any MGHead owner or any other amplifier that uses one (or two) 5751.....OK, a matched pair of NOS 1964 Sylvania JHS-5751 with greyplates, O-getter, triple mica spacers, and 1964 datecodes. in white boxes, I got a few tubes on eBay and other auctions and I just keep what I need, according to the person that I purchased them from".....the triodes were tested and MATCHED with a Hickok 6000 for transconductance, and these tubes read 1150/1150gm, 1150/1150gm. A new 5751 (12AX7) triode should read between 1050-1450gm, and the triodes are considered matched if they are within 10% of each other for gm.......this in only as a reference the only test I can guarantee is that I just test them in my MGHead and they sound very nice, both and the sound is very similar, otherwise I have no other way of testing them to verify the readings....." I will ask what I paid for them 25.00 plus the shipping...
