For quite some time ,I am now using the AZ1 Valvo meshplate, they are fabulous !
You shuld try the AZ1 or AZ11 , get the big meshplate versions, the biggest meshplates are from Valvo, Philips , then comes Lorenz , Telefunken and others with smaller dimensions.

Funny that bigger meshplates do contribute significantly towards better blooming, staging and transparancy of sound. Better even than the 80/83 mercury which I found a bit troublesome as we hav to install a separate toggle switch to switch on the B+ after the tube is sufficiently hot.

In addition I tried the 80 mercury and found the noisy and rather grainy, but yes they are better than the ordinary solidplate rectifiers.

Yu can try out the 83V (non mercury) Sylvania,RCA,Cunninghams which in my opinion are the best solid plate verwsions made by US.

Just my 2cents
Regards
Paul

Hi Paul,

Thanks for the tips. But it is hard to find those mesh plates. Does the solid plate AZ1 does the same? Those seems available freely. Any other suggestions? I'd like to experiment on this a bit.

Below is the link for my existing gird bias schematic.

#26 pre amp (check the thread 353)

Use Salas HV supply for the B+. Find the details in the below link.

Kit SSHV for Phono and Tube Pre (Simplistic Mosfet HV Shunt )

You could contact Salas for more details of PSU. Probably if you speak to quanghao , you might get the hold of the PCB for this.

For filament supply, use Rod Coleman's PSU. Contact Rod to get the parts and PCB for a very reasonable price. As well his kind support for free.
#26 pre amp

You are done and end up with an excellent 26 pre after all this. Good luck.

Thanks so much.

Sorry for my ignorance what are OA2 & OB3 in the schematic? Wich tubes do you recommend for 5Y4GT & 26?

I'm not sure the battery grid bias would work with Colemean's filament supply, has anyone tried this?
