Dubstep Girl's Massive 5AR4/5R4/5U4G Rectifier Review/Comparison! (Rectifer Tube Rolling thread) - Page 44

post #646 of 1683
Can confirm that the Psvane 274B really comes alive when given sufficient burn in, the pair I am using now have over 200 hours & they have improved markedly.

The bass performance is best I've heard.

I will have the Takatsuki's here shortly so will do a comparison with the Psvanes and the Mullard GZ34 metal bases.

Cannot wait to hear some impression on the Takatsuki, if they are indeed the holy grail then Ill have to go through and sell some tubes Ive "laid down" in recent years. :happy_face1:

I hope so too !, given that Takatsuki charge more for them than the 300B's I am thinking they must be pretty special. I find myself agreeing with Tony, the rectifiers seem to make a bigger difference than the 300B's. I have found the Sophia RP 300B's to be a better match than the KR's with the Psvanes. The KR's were a bit lean for my tastes.

Yes the Takatsuki price disparity is unusual and Ive always beleived its marketing to certain integrated amplifier designs using one 274b and a pair of 300b. As a WA5 owner, the price of the full takatsuki complement rivals that of the loaded amp itself.

 

I agree the rectifier makes a big sonic difference as well, perhaps its down to the resultant B+ output varying between different rectifiers and the circuit they're in, or maybe its pixie dust. ;)

 

I do also think that the driver tube, in my amp the 6SN7 (or 12SN7) can make a big impact. I use PS1000 primarily so I stick to british made driver tubes, to tame the peakiness of those cans.

I haven't tried the SERPs with the Psvane 274Bs yet. I am burning in another set of the replicas from Psvane on my WA5 - this time the 300B variety. I hope these 300Bs turn out as good as the rectifiers - I will be a happy camper if they are (but that would be a discussion for another thread). The SERPs have the best bass extension I have ever heard on a 300B, so the combination with the replicas should deliver bass heaven - I must swap out the 300Bs soon and give that a try :wink_face:

 

Interesting that the design of the Takatsuki 274B appears almost identical to the original WE274B, right down to the number, size and position of the perforations on the back of each plate (5). This tube looks more like a replica than a new design, but that is no bad thing, given what a great job the Western Electric engineers did the first time. If they can take the performance of the original and improve on that, then it will be something special indeed.

 

If only the pricing didn't make my sphincter twitch. How much for rectifiers...? I'm only used to being savagely raped by 300B pricing - getting the same treatment for rectifiers will take some getting used to :eek:

Both, should be here 3-4 weeks

I have received the GEC U52, and after a helpful exchange with the seller have got them operational in my WA5.

 

Initial impression of these tubes is positive, more euphoric than the plastic Mullard 5AR4/GZ34 whilst remaining dynamic.

The Fivre 5R4GY/CV717 that we talked about a few weeks ago is really nice. I prefer it to the Mullard GZ32. It is more dynamic.

yup me too don't like the gz32 with already full sounding cans, using a Philips 5R4GYS (5R4GY) CV717 rectifier now, which is really nice http://www.ebay.com/itm/Philips-5R4GYS-5R4GY-rectifier-CV717-Dutch-army-tube-NOS-/191411966048?pt=Vintage_Electronics_R2&hash=item2c910ad060
