For sale is a Cryotone tube bundle for the SE84UFO, UFO2 or used with the UFO25 with your own voltage regulator tubes. These tubes are lightly used and like new, with less than 150 hours. The rectifier has less than 50 hours. They sound great, I just found some NOS tubes I prefer in my system and these have been in a cabinet for a while and deserve to be put to better use. The bundle includes
1 x 5U4G-WC rectifier
2 x EL84-WC matched power tubes
1 x ECC88-WC input tube
Retail price is $594. Selling for $470, shipped within conus.

Also have a tightly matched pair of ECC88-WC tubes, also with less than 150 hrs. Retail is $366/pair. Selling for $260 shipped.

The pair of ECC88 tubes are sold. The Zen amp tube bundle is still available.
