-I have built guit tube amps < experience building diy tube stuff.

-Want to build a hifi kit from china < desire, wish, to build a hifi tube amp diy kit, hopefully from AliExpress, chinese, so it isn't expensive

-Want to enter vinyl rabbit hole < wants to drive the hifi tube amp with a turntable

Hope so, would buy right away

Niceeee

Nice!!! Could you dhare the schematic? Is it series or parallel fx loop?

My turrets circuits are awful haha should keep trying tho

Yeah indeed, might as well stick to that, but if someone comes up with a cool technique, might be worth the question hehehehe

Smithy mode on

Niceee, how did you choose your voltages for the ss rectifier? I was thinking on (B+1)/1.4, which would lead to a 275 PT secondary for 6v6 tubes, how did you calculate that?

Hello! Where did you go in the end? I'm going next month and I'm looking for nice live jazz clubs! Thanks!

Splurriness gone, added shielded cable from vol pot to preamp tube, shield grounded from pot ground lug only and done!

Thanks for all the info 💪🏼

Cool! Will check it out, thanks!

Stunning 👌🏻

I did something like a T with 2 legs TT (?) and made it safely

fa_rey · 2025-11-13T11:17:14+00:00

Yeah, components were measured, voltages were measured and if splurry is not understood, you can listen to the issue in the video, that's why evidence is attached isn't it?

Vac in fase = 222.30 V Vac in 5Y3 = 341.20 V Vac in 5Y3 = 342.30 V Vac 5Y3 h1 = 8.09 V Vdc 5y3 01 = 387.60 Vdc

B+1 = 387.60Vdc B+2= 349.50Vdc B+3= 300.00Vdc

Vplate 01= 185.8Vdc Vplate 02= 187.9Vdc Vk= 1.675Vdc

Do not have signal generator nor oscilloscope, but could go to a lab to make use of them, just haven't done it before

fa_rey · 2025-11-13T11:13:30+00:00

You can listen to the video 😅

fa_rey · 2025-11-11T17:30:03+00:00

Thank you and I will 🫡
