My experience with baking 2" tapes comes from my experiences at Warner
Bros. Studios, Burbank, CA. As Richard Hess said: "456 is the poster
child for SSS" so, don't ask, just bake it.! Regarding the question of
how long to bake is dependent on the size and type of oven, the number
of tapes to be baked at one time and (obviously) the condition of the
tapes themselves. The oven at WB is commercial grade, capable of baking
34, 10.5" reels at a time. I've baked as few as two reels on up to an
oven full. For two reels of 2", the average baking time is 18 - 24
hours. I would suggest that you only bake as many tapes as you can
process in a day so that the stabilization process is as fresh as
possible. You mentioned leader breaks. Expect any splices to have to be
replaced after baking. Not always the case but, build the labor cost
into your budget.

One tape of interest I have with me, destined to a comrade here in town who is as passionate about vintage audiotape recovery as we are with videotape, is a 24 track on "Ampex Grand Master" 456 from 1988 in a cardboard box. It has track assignments within. The tape has leader breaks. In a test of sorts, we are going to link this up with a 1" C of the concert (same production, same date) to create a new stereo mixed version. I've done this before so I am familiar with the routine. The question to you two (and others) is: What should we expect from a stickiness standpoint (if any) from 1988 vintage "Grand Master" 456?
> The client has multiple reels of this concert so this is a test of sorts. The 24 track will create a ProTools session for the mix down and new stereo imaging (5.1?), to be done at the client's facility. I'm going to be remastering the 1" C today to file (it too is in stereo albeit with weak L-R imaging as viewed on the phase scope). It's a full orchestra with choir.
