Thanks Jaakko. I forgot to mention the monitor attenuator is 10k input impedance 5k output impedance. Shallco could only figure out how to do it as a full T pad. I had asked for a bridged T to save four decks. 12 decks for stereo.

Love the 1" Studer half-track preview.   

Curious about the Shallco...     Regular bridged H-pads are 4 decks for 2-channels (balanced).    You have preview and program (ergo, 8 decks?)...   What are the four extra decks for?   Also, why is the output Z different from the input?   Thought the T's and H's were symmetrical wrt i/o Z...   

Thanks,
     Andrew

It's not a bridged H, it's a full H. Four more decks for the same number of channels. I wanted a 10k:5K impedance ratio. It's the best compromise I could think of for a passive attenuator. It presents a bridging load to the monitor source and lowish enough source impedance to the monitor power amplifier.

So much for that "confounded bridge!"

I'm a little surprised no one asked the obvious question. "Why would you do something so stupid? No one will ever use it". The answer is "I know, I did it because I wanted to".

Same with the console. Tons of blood and treasure in. Absolutely no resale value out.

To be fair, I've been trying to rationalize getting a 1" conversion for my A80 for some time now, so while the through crossed my mind, I was shamed into not asking it. hehe

That said, I think I've had one client ever ask if I could handle 1". I've always figured I'd just rent a unit if it ever came up...

I had Mike Spitz add the 1" mechanical conversion to my ATR but I didn't buy the headstack - I rent that when needed from Blackbird (which is not too often).

Are the knurled knobs behind the heads custom vernier azimuth adjusts or little grab-handles for the assembly?

Stupid ?
no Paul
first it looks like a child dream wich is great to realise ! ;)

second there'll be one time where almost no facility will still have AB vinyl transfert console and such tape players with preview and program heads running fine

than you'll be the one !!!

one of my favorite "modern" vinyl is AAA,
LOW, Trust ,
and it's one of the very best sounding in my collection.

Finally a view of the console! Awesome Paul, i know you have been working on it for a while.
What frame is that?

Btw, you still have that powder gun?

Yes.

I was only kidding...   

Domine spectabilis!  This machine should be named, Hrunting (the sword which was used by Beowulf to slay the grim Grendel...   Just don't use it to play any tapes by Grendel's mom!   (;    )

Tell you what, Paul, it aint just Hedwig who's gonna be angry about that inch you just had made...

I had the frame made. It can be filled with sand. The open sides will be plugged up with fabric stretched across frames. The frames will attach to the lip of the cutouts with velcro. It's two sections that bolt together with the arm rest and over bridge length to form the middle section.

I have the powder gun but I don't plan on using it. Setting up a booth/box with good ventilation is work. My workshop is windowless and packed. I've decided my energies are best spent elsewhere. I think I'll give it to the guy who made the frame. I'll want him to make me a matching  rack or two eventually. He sent the frame out for powder coating but wanted the gun.
