Is that a 53ku sorry eyes no good any more, if so must be very sweet never heard that rectifier cool..
Some more Solid State mucking around.
Tried one of these:
Sounded the same as the other Solid State rectifier which is really nice. However it had the same over heat issue where at 2 hours the whole amp gets very hot.
Then I got the Weber Copper Caps (ordered two).
This is the bomb. The best sound. Everything is better than the best tube rectifier I own (Takasuzuki 274B). Sweeter clearer treble which produced more detail. I heard things in my favorite tracks that I hadn't heard before. Alison Krauss's New Favorite. Her voice croaks on some high notes. Never heard that before. Noise level is extremely low. Just not there at all. I've always had one of my drive tubes (TS RP 6C8G) that on occasion got a little buzzy/hum sound. Not a bit of noise from it last night. I've noted some rectifiers work better with the other tubes in the amp. Solid State kept them all dead quiet. I would guess good clean voltage keeps the other tubes happy. Holographics and soundstage sounded as good as the TAK274B. Bass deeper and clearer. Speed was excellent. Not as quick as the other SS rectifiers but better than the TAK274B. I'm not too worried about speed. It sounded good enough and I don't listen to a lot of lightning fast music.
Music in general had more snap and sounded far more natural.
With the amp on for three hours the amp was warm. No heat issues. Normal tube rectifier makes the amp hotter.
I adore Weber's Copper Cap. May look odd however it sounds amazing.
Is there a reason you decided on the 5U4GB instead of the WS1? Just looking on their site it looks like they recommend the WS1 for "hi-fi amps" and only recommend the 5U4GB for guitar amps.
We have a small supply of NOS (new old stock) Tung Sol 5998 on hand right now. Send an email to info@wooaudio.com if you're interested.
There is not much difference electronically between them. I went WU4G as it is closest to a 5U4GB which the WA22 circuit is designed for. WU4G has been said that it is closest to a tube sound as far as pacing/speed goes. WS1 will have a faster pace. More SS type of sound.
A slower more relaxed pace is more my taste.
If you contact Weber and ask they will also recommend WU4G. They designed it as a drop in replacement for 5U4GB.
Either will be a good choice.
I've not yet tried the Weber copper cap WU4G is this thing really worth giving a try? thanks..enjoy guys
Yeah it is.
Think 596 with more bass and better soundfield.
