Combined Shipping
I can combine multiple items into one package and ship them for a flat rate.
In many cases, eBay's system allows you to combine multiple items for a flat rate, but for some countries, the system often doesn't allow you to combine multiple items purchased. 
Don't worry, you can.
Contact me and I'll explain how we can do this for you using a flat rate.

ULTRA-LONG LIFE
TOP QUALITY CONSTRUCTION AND SUPERIOR SONICS
⚜YEAR OF CONSTRUCTION 1957 - VINTAGE SERIES⚜

Not everyone knows that this tube has very similar characteristics to the 12AU7; the gain is almost identical, and it is also very similar to the 12BH7.
We have tested this tube in hundreds of amplifiers using 12AU7s, and 100% of our customers prefer this 6350 tube because its performance is superb, with significant improvements.
These are tubes of extremely high sonic quality, superior to the classic 12AU7 or 12BH7.
Many of my customers who own Kondo or Audio Tekne amplifiers, or other brands, 
have permanently replaced them.
