BHK pre signed by Bascom



Hi Paul,

I just purchased one of the first 50 preamps signed by Bascom, still new, from Upscale near me in CA. Have there been any hardware updates that would warrant sending it to Boulder for a refresh?

It will be the meat in the sandwich between DS Sr. and M700s.




Nope. The same.


Thanks Paul. It was an extra special bonus when Kevin Deal said he had a signed one he was willing to part with, plus the 2 pairs of the Tungsram PCC88 that Bascom likes a lot.

Do you recommend I burn-in with the stock tubes for a couple hundred hours before rolling?


The first thing I do is fire it up, turn it on from the front panel and let it stay on overnight. From there it’s good to and will get sweeter over the next few weeks.


Excellent use of the “solved” button!


Today, at 65 hours, stock tubes, the BHK pre began producing a significant increase of very pleasing bass slam!

Depeche Mode Violator is resonating nicely throughout the space,

Very pleased with the acquisition of the BHK, thank you PS Audio team.
