Pair Silverton UX-245 (45) tubes

Nice matched pair for structure and near match for strength.  

UX in the name usually is an early 1930's nomenclature before they move to just '45'.

Test at 70 and 74 where 47 is pass/fail on my calibrated TV-7.

After you place order I will send you a PayPal invoice that add $25 for UPS ground shipping fully insured.
