I have to ask why any one would want to build a new stack for a
Gulbransen player?  There are an awful lot of these beasts around that
nobody really wants.  For dozens of years no tech would even consider
restoring one, they would opt to replace the stack with some other
type that they would retrofit to work.  I recall seeing a ton of these
laying around in a Chicago shop after the old technician died.

The effort involved in simply rebuilding the old Gulbransen stack is
far less than building one from scratch.  Gulbransen used the best
materials in their stack; all the wood was maple and reproducing this
would be extremely expensive, and that's not counting all the wood
working involved.

I must admit that they are a pain in the rear to restore but once
they're done they are great little units.  I have restored dozens of
these and I'd still rather do a Gulbransen than a Schulz or Werner or
Brinkerhoff of the older variety.  There are a great many Gulbransen
players out there with no guts in them anymore and there's a good
reason for it.
