Identify a Resistor in an Audio Research PH3


In just acquired an Audio research PH3

It came with two nice looking Vishay load resistors - But I can't identify them.

They say 

Vishay
VTA55
B9T15

that's all. I can find a stat sheet on VTA55 - but the B9T15 isn't enough for my magic decoder ring..any ideas?

Gracias!

My magic decoder ring agreed with your findings. Only a spec sheet for the VTA55 and nothing for the B9T15. A quick call to ARC support should yield answers. 
OK, thanks folks - I guess I will need to take them out and measure. can't figure out why the markings would be so incomplete!
