I'm digitizing tapes that I hadn't run since the early 1980s. They include
15 ips transfers of the early 12" shellac pressings from two batches.
There are some redundancies, so I have the luxury of choosing significantly
superior ones. The inferior ones were in poor condition and so warped that
they had to be run @ 33.33. Those sub-masters were then run
(theoretically) at 35.22 ips. Dolby-A 15 ips masters. EQ. was not
adversely affected because the transfers were done FLAT. Fortunately, I
did voice slates for each episode, citing the episode #, master #s & air
dates. FYI the way that I set that speed was to feed the closest possible
frequency (ideally 11.269 KHz) that I could set on my Leader oscillator
into the reference input of the Ampex servo circuit (4.8K for 15 ips).
Those DC capstan motors run up to just under 45 ips, so doing this did not
'stress' the system.
I've posted a 2 minute comparision of a Marsh recording with a later one.
Both samples are FLAT. It clearly demonstrates the quality differences.
That of course could be done with any of the Gosden/ Correll Victors, but
this is a more historically and technically accurate indication of what
radio listeners might have perceived when the change in vendors occurred in
'29. Lacking in each of the slates for the post-Marsh recordings is the
identify of the successor recording company. I recall someone years ago
telling me or surmising that it was Brunswick. Perhaps the "LTR" master
prefixes are the critical evidence. If any of you can with certainty, cite
the identity or identities of the successor recordists, then I'd appreciate
learning that info. Also, the quality differences also due to the Marsh
pressings being very inferior to the later ones.
FYI episode 339 for 04-25-29 mx 5808 & 5809 is the 'most recent' of the
Marsh-recorded sessions that I have. The earliest post-Marsh episode that
I have is #383 Saturday, 6-15-29 , mx LTR 116. This was a single sided
disk, part 2 only. Side 1 was missing from that batch. I assume that pt1 1
was LTR 115. So if it's not known when he vendor change occurred, then at
least we have a window.
I assume that opening & closing scripts accompanies the disks that were
sent to radio stations. IF that's correct, then are any known to still
The sample's graciously posted by Mark Durenburger. So those maddening
access issues with "PlopBox" will not inconvenience anyone who wants to
hear this comparitive sample. It contains the episode & master #s &
(spoken in my relatively youthful pearly tones in the early 80s.)
