I have a pair of Hashimoto H-20-7U output transformers.
Specs:
Output: 20W at 50Hz
Primary: 5K or 7K Ohms
Secondary: 4, 8, 16 Ohms
FR(+-2dB) 25-70,000Hz

http://www.tube-amps.net/Hashimoto_Products.htmThe deal is, I bought these for a project a little while back and I should have asked more questions as these are not appropriate for my big GM70 monoblocks. They have the requisite 7K primary and are rated for 20 watts, but are not gapped for really high current that a GM70 requires. The 5K primary would be ideal for a high-end 300B amp. Then again if you are looking at this ad, and know what these would be used for, I don't need to explain all of this.
These were only taken out of their original boxes to examine. They have never been used, never been soldered. Exactly as new.
These cost $530/pr + $80 shipping (from both tube-amp.net and ebay..same guy). I'll eat both shipping costs and offer them for $500 shipped w/i cont'l 48. I am not forced to sell and would rather keep them for some other project than take a bath on them, so my offer is firm. Thanks for understanding.
