6ba6 GR tubes

So you liked the 6ba6 version better?

cool layout.  link switch?  or permanent stereo?

I decided I didn't want a link switch so its just a dual mono unit...

bluebird,

Nice... but what the hell is that GIGANTIC RESISTOR ? 

Yea, I work in an electronics surplus store so I have a lot of over size things at my disposal.
I just wanted to dissipate the heat through more area. I also added the two fans.

Yes, much better.

Careful getting Porcelain sockets from Tube Depot - turns out those WERE plastic.  Something with their part numbers and stock was messed up.  They're sending replacements.  Just thought I'd mention it if anyone was ordering.

so could you elaborate on 6ba6 tubes?

Great; have been suspicious of mine which I've had for 6 months now.  Time for a closer look.

Thanks in advance.

Oh and are sockets for PM670 and D-AOC the same??

 

[[silent:arts]]

this one looks good
the ones you posted will work in the D-AOC.
sadly they are not the same

Thanks Volker, Just to clarify, the link you gave is for the PM670 and i would need 8 pieces

And any of the 3 links i posted will work for the D-AOC? which 1 in particular? believe the dimensions for the 3 are different...

Sorry to ask, but just want to make sure before i put in the order.

 

[Siegfried Meier]

What?  I'm confused...why would they not work?  Won't any 9 pin ceramic socket work, with maybe a little fitting in?  Or am I missing something...

the PM660 sockets are smaller than the usual ones I use like in the D-AOC or D-LA2A.
footprint and diameter are different and smaller, haven't tried to fit one.

It's explained here. http://www.groupdiy.com/index.php?topic=29056.60 Let's that continue there because it's a pimp 

 

[Jonkan]

Can someone check for me if this is the correct type of noval socket? im not to familiar with what different types there are available.

Question about the XLR's guys.  The BOM says to use those NC3FD PCB mount type XLR's, and I see that they have pin 1, 2, 3 and G.  I'm not mounting my XLR's directly to the boards, but using long pins to connect them (already cut and mounted XLR's a long time ago).  The board has solder holes for 1, 2, 3 and G, so if I use a standard XLR (if I even can), what goes to G?  I noticed the pic above has this done, but I can't tell how exactly.

Thanks!

Hi,
here are some pictures of how I connected the relay bypass boards with standard XLRs.

hope this helps
regards
Bernd

 

[Siegfried Meier]

Cool, thanks for the pics - so that ground pin is not needed then.

Thanks a bunch!!
Sig

 

[[silent:arts]]

the ground pin doesn't have any connection to anything on the bypass PCB.
there are jumpers to ground as an option.
but I prefer to star ground them without using the jumpers.

Damn.... 

I have already solderd mine in and didn't realise.
Will the plastic ones be OK?

I don't wan't to fork out another $50 for tubes and shipping.

 

[[silent:arts]]

don't know what happens to plastic sockets if they get too hot - melting ?
but we are talking about a very hot peace of gear ;D
