I was able to acquire a full set of new matched tubes from ARC last week. (REF6SE) $1200 including shipping. I did have to wait a few months but my current set still have some good life in them. Good luck…!
REF5SE tubes
Time to retube. If tube’s direct from ARC and NOS tubes are not in the picture, what would be next best for tubes? Haven’t purchased anything from Upscale , so that’s out.
Appreciate any and all advice.
