Customer evaluation for "Psvane 845B-HiFi Series, mica free (NEW)"

Great 845 tubes that won’t break the bank

First up TAD are superb to deal with. Great advice and fast, safe shipping.

I have Cary 211’s, so with a quad of 845’s and a quad of 300b’s I can’t stretch to “super tubes”, but the Psavne 845 are a definite upgrade to the standard Shuguang 845.

More details, more controlled bass and the workmanship looks top notch. Very pretty tubes and not having the mica gives a great view into the tubes.

Not quite the big jump written about on the old positive feedback review, but still an improvement. Don’t believe the 6 hour burn in from that article either, took them 60 hours to settle down and lose a bit of hardness. After 60 hours they are superb.

Recommend if you can’t stump for the top of the line for whatever reason.
