Curious if anyone here is using a solid state rectifier, If you are, do you like it better then a tube rectifier?

Yes and Yes

I have had my st-120 for over 10 years and it's been great sounding and very stable.

Re: Solid State Rectifier?
any other changes need to be done, after replacing the tube rectifier to the solid state rectifier?

I got the weber WS-1t (thermistor).
You may want to get the delay board. It makes life easier for the power tubes. The rectifier tube comes up slowly where as the s/s doesn't.
If you search the forum, you should find more details.

I use the WS-1T. also. There may be an improvement in sound with a Mullard tube rectifier, but the WS-1T is far from the weakest link in my system, so I doubt if I would hear the improvement from the Mullard. I mostly just want to play my music, and I read that a failed rectifier can cause other components of myamp to fail. For general reliability, I chose the soiid state rectifier. I do have the delay board, and am thinking about adding an auto bias board. Not sure where I would mount the auto bias in in my ST-`120. If anyone has photos or a description of how and where to mount an Autobias board in a VTA-120 with Time Delay Relay , I would really appreciate it. The underside of my VTA-120 is pretty tightly packed.

You need to check and adjust Bias after changing rectifier tube or changing to a solid state rectifier.

From what I've read, you don't need the delay with the AB board as it has a built in delay. It bolts in under the VTA board on included standoffs. This is my ST120...
There are many pages of this thread on this forum.

Re: Solid State Rectifier?
If you do a search, you can find the AB manual online. Try searching ST70 auto bias or something in this vein...

How would the Mullard have an improvement over a non sagging WS1, when the tube rectifier still has sag ?Hops wrote:There may be an improvement in sound with a Mullard tube rectifier

I have pondered this as well.
I think some people simply prefer a little sag is the only answer I can come up with. Well, other than electrons that pass through a vacuum are naturally happier than those that pass through a semiconductor junction, and everyone knows happy electrons make joyful music? Also, they tend to produce a warmer sound because it's hot in those tubes
