[EDIT]

I’m updating this post not to make people confused. I believed B+ is lower with 5v4g than 5y3. but 5v4g is increasing B+ and makes the bias warmer than 5y3. I guess it is the reason I feel the amps are more alive with 5v4g

and, I noticed the vintage amps still have the original caps from 50’s and early 60’s are more vulnerable with 60hz hum. I’m just guessing leakage of the coupling caps and the filter caps could be the reason. I’m still enjoying 5v4g with the amps with new components. and didn’t have an issue with my 5D3 which has new filter caps. the old Astron coupling caps are still fine with the DC leakage in it. 

there are more info for 5vg and 5y3 rectifiers on the gearpage.net the people there have more and better info

I hook up tweed champ, deluxe, and m-track 2×2 together while I’m playing with youtube music. 5v4g sounds still alive with this stereo and digital setup to me. m-track 2×2 is sharing the one single full bandwidth for usb and instrument input. it sounds good only when you turn the knob to USB or Direct. it sucks when the knob is the center. maybe it’s the reason it’s cheap. 

it’s the knob on m-track 2×2. don’t buy it if you want to use your guitar amps as monitor speakers and, still for your guitar at the same time. maybe I’m just doing this wrong.

    after back and forth between 5y3 and 5v4g for a couple of weeks. I'd say 5v4g is good and practical for champ and deluxe

tried 5v4g with this modern 5F1 with 10″ ceramic speaker in 5e3 cabinet. and it seems to be the right place for it. I prefer 5v4g with tweed deluxe to tweed champ. it could be the size of the cabinet and the speaker I guess from this setup. 

one good thing with modern 5f1 is all the components are new or NOS and it has almost zero 60hz hum. I’m going to exchange 2 prong cable to 3 prong on my old champ and try 5v4g again with it.
