en I’m into 5v4g than 5y3 with 6v6 tweed amps

[EDIT]

I’m updating this post not to make people confused. I believed B+ was 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

then I noticed the vintage amps with the original caps from 50’s and early 60’s are more vulnerable with 5v4g to 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. didn’t have an issue with my 5D3 which has new filter caps either. 

[EDIT again]
one of my 5V4G tubes shows very low B+. the 60hz hum came from it I believe

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

I hook up tweed champ, deluxe, and m-track 2×2 together while jamming with youtube. 5v4g sounds still alive with this stereo and digital setup to me. but, m-track 2×2 is cheap and sharing the one single full bandwidth with usb and instrument at the same time. it sounds good while using only one of them. it sucks when the knob is at the center.

it’s the knob on m-track 2×2. don’t buy it if you want to use your guitar amps as monitor speakers while playing guitar through the direct input. 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 style 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.

I’m guessing the 60hz hum I had came from this dying 5v4g. just noticed one of my three 5v4g tubes shows 307v B+ with 5D3.

377V with Bendix 6106 5y3wgt which has purchased as NOS and less than 1 year old 366V with Hytron 5y3wgt which is many many years old 369V with GE 5y3gt less than 1 year old 393V with GE 5v4g which I purchased as NOS and less than 1 year old 396V with RCA 5v4g as …

  • en 50’s Jensen P12R restoration has begun

  • a close friend gave me his NOS or like new silver p12r speaker for my tweed deluxe 5d3 a few months ago. then I got me a P12N which I like for the last 15 years. 

    but, I couldn’t help myself to search the original p12r with the bell. I mean p12r from the same era with the same color.

    I dropped by his place a couple of days ago. he showed me this p12r pulled out of his 5C3 a while ago. it was the present for me and my 5d3. I ordered a speaker cone looked like the original even before I knew he had this. and I like the black switchcraft 1/4 plug which I’ve been after.

  • en Is cloud gaming the future of online video games?

  • French start-up Blade thinks it has what it takes to succeed in the space. Its cloud gaming service, Shadow, aims to bring the experience of playing a powerful gaming PC to any device, be it a laptop, tablet, phone, or smart TV. Blade’s goal for “Shadow” is substantially more ambitious than any of its peers. Rather than creating a service that delivers content, it wants to replace your console or gaming PC entirely. Booting up Shadow serves you a virtual Windows machine, which you can use to play your games on Steam, Origin, Humble, and Itch.io. The games purchased by yours, and yours to keep, from the standard storefronts. Your Shadow machine is just like any computer you’d own, except you can access it on any device for which Blade has created a client, including Macs, PCs, iOS, and Android devices. Shadow also works directly on Sony smart TVs through an Android client, and a client for Tizen-based Samsung smart TVs is on the way.

    The goal of all this is bold, yet simple. Blade wants to make the home PC obsolete. You can find more informations on their website:
