Hello all. I use this tube instead of the 12AU7 in the cathode follower position on the ZP3. HUGE upgrade over the stock tubes.

I bought these from Upscale Audio. Originally bought 3 ( which I am keeping ), and then 6 more for the phase splitter on my Woo Audio WES. After playing around with RCA/XLR adaptors, I will no longer be using the phase splitter and now have no need for these tubes. 4 are brand new and two have 4-5 hours on them.

Cost me $ 88.88 each and worth every penny. Here's the deal.
For the new ones:
65.00 each, or
125.00 for a pair, or
240.00 for all four.

For the used ones:

55.00 each or 100.00 for the pair.

You guys get first crack before they go on the 'Gon or Ebay.

Cheers,             Crazy Bill

BTW. Upscale Audio is out and these are nearly impossible to find now.

Just none out there to be had in this condition.

PayPal only.  Shipping on you except if someone buys all four, then it's on me.

PM sent

All gone.
Many thanks to those forum members who purchased these tubes.

Cheers,           Crazy Bill
