Bastard .............of course i mean that in the nicest way but
yeah we been missing a dual stage around here for a while [ servo ? ]

and a hpf is something i often can use , how about variable
or is that a compromise or just needless extra parts
[ i don't need front panel xlr , so there's room '

Love the silver look or is that platinum ?

Greg....
Now there's a surprise... you wanting to change something..!!
But you could make your own metalwork, dump the xlr/jack combo, add a dual revlog pot and jack socket and you're off.

Snatch.... It's an xlr/jack combo.

Ah , but i couldn't do it as well as you , you don't want to serve me ?
gentlemen bow do they not ?

The 1/4" is more likely and the combo makes sense so
that's understandable , where is the hpf freq set at ?

and no servo ?  Still looks very nice

What was the inspiration for those DOA? They look remotely similar to something I've been working on.

What no cup holder? Looking awesome, dual stage with trafos and opamp is a great combo for 500. How do the gain stages differ? What sort of trafo options for these? Kits to come :) ?

Serve you?  What... like stick my knob in your ear and rodger some sense into you?
Gentlemen bow?  What are you on about?
The frq can be set wherever you like.
No servo... you're absolutely correct.

No cup holder Im afraid, but you can stick your ciggy in the jack socket.
No difference in stages, but you can stick another pad in front of the second to taste.
Input options are currently (and most likely going to be) Stevens & Billington or Sowter only. Output'll be a much wider choice.
Kits most certainly on the horizon.

It continues to look good ,
and you're much more of a man than i am
[ one day , maybe i will design a pcb ................
or just buy more of your's ]

Personally i wouldn't need the xlr but i can understand that the combo
jack serves a dual purpose more bang for the buck for others
Do you have a sense of people's preference in this regard ?

And a hpf is something i often need on the live to 2trk & remotes
but often saves headroom & bandwidth on mutli trk as well
this is variable now ? shall i order more ?

And Still , the only dual opamp offering in a 500 series in d.i.y. i believe ?
at the very least i'll take a couple of boards if not kits [ Damn dollar exchange ]

thank you Peter
