On occasion I revisit a bunch of different rectifiers I have used in the Select just to see if I'm being a snob about the Mullard gz32, but can find nothing to compare to this one.

The closest candidates are a couple nos RCA coke bottle 5v4's which are superb; but these still can't compare to the fluidity of the Mullard. The 5u4's aren't bad but are quite a bit more hard sounding in my particular system. The bass region is thumpier with the 5u4's, however.

Nice one Keith

You can try one of mine in your Taboo tomorrow LOL

I now have 2 X 5U4, a Mullard GZ32, 2 X ultron GZ32`s and a single 274B

Got to agree with veryoldcat the Mullard is the pick of the bunch

mullard gz32 are really good
i have collected 5 NOS in unopened boxes

one rectifier that nobody talks about here is the
brimar 5R4GY it goes under a range of different brands including stc, ultron, etc , kicks the butt out of RCA 5R4GY IMHO

here is a link so that you can have a clue, important factor is exposed wires inside at the top of the rectifier, the closed one is good but not as good

not as fluid as the OLD mullard gz32, but better then the new mullard gz32, very very musical crystal clear sound with incredible sounstage (shocking when compared to RCA's). i just can't decide between the old gz32 and the STC 5R4GY. questions questions

Not sure there is a downside, other than with them being used, they MAY NOT last as long? also maybe they do not quite test up to new standard....... but hey if you prefer them to the stock valve, how bad can they be?
