I just wanted to circle back to this thread with an update. I had ordered a matched pair of the Psavne Acme 845 tubes back in July thru GD-Audio Parts via AliExpress.
They arrived packaged very well, they sounded absolutely fabulous in my amplifier with the exception of one of the tubes making a horrible noise. Alightronics suspected that one tube may have become damaged from the overseas shipping and suggested that I return them.
Trying to return them via AliExpress was a very stressful experience for me, partly due to me being technologically challenged. However, they did accept my return and granted me a full refund.
Due to the wonderful correspondence of Alightronics on this forum, I decided to place an order for another matched pair of the Acme 845's. They came and are playing absolutely beautifully in my amp and so far (fingers crossed) without any sense of defects.
They play wonderfully dynamic, full bodied, holographic sound staging, and with great refinement.
I appreciate the support Alightronics has provided on this forum and hope to see them come back as they are a true asset to us.
Best wishes,
Don
