Is this available anywhere online. I'm upgrading to a VTA pcb, and replacing everything but the chassis and output transformers so it would make my life much simpler to have the VTA kit manual rather than just the VTA pcb install instructions.

VTA Manual
Hi --- At the bottom of the Tubes4HiFi Page "http://www.tubes4hifi.com/ST70.htm" are the following Links:
There is a colored high res picture of the interior of a VTA70 Chassis.
Here is a Colored Wiring Diagram --- very usefull!!!
http://www.tubes4hifi.com/VTA70wiringdiagram3.jpg
Here's an older page showing step by step conversion of ST70 to VTA70 with the VTA mod PCB
http://www.tubes4hifi.com/VTA70install.htm
The older page has the text but the pictures are blank. You will have to send an email message to Roy Mottram and see if he can reload the Link. When it is reloaded, you can do a SAVEAS to your hard disk and you should a usefull copy.
Roy's email address is: roymottram@yahoo.com
Hope this helps.

Re: VTA assembly manual
I've seen those and found the page linked to below. I'm just hoping to get a copy of the whole thing.

Re: VTA assembly manual
I have a 5 page document here that details "Replacing your stock Dynaco ST-70 with a VTA CCS driver board". I will see if Roy can post this on the Tubes4hifi web site.

Re: VTA assembly manual
I have that, which came with the new board. I'm just about finished completely disassembling and cleaning the old unit, and thought it would be simpler to build from one VTA kit instructions rather than parts of the VTA driver board instructions and parts of the st-70 instructions.
As is, each step involves following the st70 instructions, cross checking with the VTA instructions to make sure that's not something I'm directed to undo, and using the diagram mentioned above to double check.

Re: VTA assembly manual
also, just in case it wasn't obvious, a manual for the VTA driver board comes with PURCHASE, otherwise, it isn't available from Bob or myself, due to the proprietary circuit design.
