For sale is a pair of cryo'd and matched 6H30-DR tubes built in 1991. Brendan at Tube World was kind enough to offer me these from his private stock back in 2008 after he had already sold out of the 6H30 stock he had then. I ran these in my Modwright Transporter with tremendous results, but not long afterwards I ended up moving apartments and never fully put my system back together; I've been selling my system off piece by piece since then as I am slowly moving back to a headphone rig to save space. Conservatively I would say I put 300 hours on the tubes over the course of four months- there is plenty of life left in them. If you have a Modwright Transporter or a 6H30-capable preamp or source, these should serve you very nicely.
SOLD including USPS Priority Mail shipping to anywhere in the CONUS. If paying by Paypal I will absorb the 3% fee. Please PM me if interested.
Note: I also bought a 1959 GZ32 rectifier when I bought these, and as you can see, I think Brendan mistakenly filled out one of his labeling stickers with the GZ32 model number and date before he realized he would use that sticker for the other 6H30 he was selling me, hence the odd mislabeling on one sticker. The tube testing results on that sticker however are accurate.
Also, if you are interested in purchasing these along with the GZ32 rectifier for a fantastic MW Transporter tube setup please let me know and I can put together a package price.
