DIY Sony VFET Builders thread

Pix of the chassis posted in the main thread

Perhaps this section is best left for technical build questions etc. (?)

Enjoy music

Anyone have dimensions for the chassis interior? I'd like to get started planning my internal layout while waiting for the goodies to arrive. Still no shipping notifications for my chassis or parts kit.

External dimensions were posted some time back by Gianluca from Modushop, but there has been so much traffic in the main thread that the information is difficult to find. It is a relatively small chassis, which has a significant amount of internal space taken by the mounting brackets for the output transistors. I wouldn't recommend planning any interior additions, except possibly for some nice motor run capacitors (much loved by Zen Mod), until you have received yours. Some who have gotten their hands on one already have suggested doing as much internal parts and wiring assembly as possible before bolting the heatsinks and baseplate together, as there is little room for one's hands.

Hi, Not sure about the interior dimensions, but external dimension are well known 🙂

Rough dimensions coming in at a very tidy and svelt—
in inches:
11.5 Wide x 12.5 Deep x 7.5" high from the floor

metric:
292mm W x 318mm D x 190mm H

Add some depth for the VERY nice jacks.

Incidentally—around 115F on the top of the sinks, dropping to mid 90s midway down, about 108F on the body of a Vfet. Brick is tepid to the touch. Sweet! Been running this for a couple of days, all types of music. Vinyl and hi-res digital (plus movies)—it's fabulous (and an honor to get to play it ahead of the curve so to speak).

Gianluca confirmed the Heatsink dimensions: 300 X 40 H 165 mm

Thus, considering pfarrell numbers, internal dimensions should be: 210mm W X 300mm D X 165mm

Hopefully, Gianluca will confirm these dimensions. 🙂

Got it, thanks guys - much appreciated. I guess I'll hold off till I have mine in hand, and see a bit better what kinds of additions will / won't fit.

In the spirit of documentation and sharing, here’s a completed OS

(Yes, I made a part substitution - had to at least make one thing different 🙂)

@ Codyt Delicious
So how FE card completed looks ?
Haha Greedy Boyz 😀 Thanks

Ha, I’ve only had time to squeeze in the OS boards, then my family came home. Won’t be able to get back to it until later this weekend 🙂

Haha first SE Vfet amp play music Sunday ? 😀 Greetings

I was reminded how quick they were when checking the position before install. Several K can go by pretty quick 🙂

I think the people with screws will have a jump on me. In fact, I’m kinda glad I don’t have the screws yet. Forces me to slow down and enjoy the process even more. I want to savor this one 😀

Cody, I predict you’re at Home Depot buying an assortment of M3 and M4 hardware when they open tomorrow!

 

[MEPER]

The M3's for the top/bottom cover are hex-types.....thread length about 10mm.
It will look "pro" compared to "philips-head" screws.....

Believe me, that though has crossed my mind... 😀

Papa has done most complicated part, the rest of the kit work for Diyers is a top cherry on the cake.
Class A, triode transistor, no feedback, nice frequency response bandwidth,
front-end with jfets buffer and audio input transformer = cute amplifier with character :^)

Question: Who show us the completed kit amp first Tadada

 

[codyt]

FE’s down, PS filter to go 🙂

@ Codyt

🙂 Stimulating!
