Things to consider with the ARC VT130.
Made in 1995. Has it ever been recapped?
The amp requires tube biasing adjustments. (Power tubes as well as, I believe, the small signal tubes.) Do you have any experience biasing an early Audio Research VT series power Amp? I believe, the VT130 requires the small signal tubes must be biased. I have a pair of ARC VT50 amps. Biasing the signal tubes can be a real pain in the ***, is an under statement.
I would find out for sure if the signal tubes require biasing when installing new signal tubes. Especially the driver tubes.

Edit: I could be wrong in saying the small signal tubes require biasing.
A quick look at the schematic I didn't see any adjustment pots.
