813 socket dimensions

Gluca · 26th January 2006, 04:36 PM

Ciao,

I am putting 20kgs of stuff into a metal box pretending to build a 813 SE amp ... sockets are still to be ordered and I could not find anywhere info about their dimensions ... anyone can help?

From the RCA 813 datasheet:

Base.... Medium-Metal-Shell Giant 7-Pin with Bayonet. (JATEC No.A7-17)

Theres one at the bottom of this page.

www.tubesandmore.com has got them too, search for 813.

Build Ultranalog.com ColdWar with these with some Mazda 832's.
Few year's ago. Very nice amp.

Be carefull, when mounting these sockets. They are not always
perfectly flat. Thightening the screws to much is recipe for a small
disaster.

THX. Dimensions seem to fit perfectly with the other parts.

Are 6C33 and 813 using the some socket? On some www they are listed as different ...

Unfortunately not . The 813 has two pins larger than the rest. You may try to make them larger by using a drill but I belive it would by better to find two original sockets.

Thx, I supposed it ... looking at the socket's pics and at my 813's I noticed something different there.

I believe I will need to buy them overseas ...

Just asking, what topology are you going to use?
Any preliminary schematic?

Just to scratch the surface

801A choke loaded, later on I will add an 807 as srpp leaving the choke as load

6uF paper/oil

1:2 step-up autoformer

813 SE bypass a la ultrapath; I think I will upgrade the OPT and go parafeed later.

Not pretty sure, I am considering to have PP at the output stage ... leaving room for that.

Heater will be DC (current regulated)

I think I will use svetlana 6D22S in the PSU. Got plenty of motorrun caps.
