First don't have a copy of the book "My Week Beats Your Year".
Anyway did some searching about Tobler's 1971/72 interview [originally planned for Zigzag]
Zigzag wasn't published between 1971.Dec [#24] and 1972.Aug or Oct [#25] - info from
http://www.45worlds.com/magazine/issue/zigzag-25uk and beatchapter.com
In Zigzag #25 [1972.Aug or Oct] is a cartoon "I'm Waiting For The Man" by Nigel Trevena [republished in his 1973 book "Lou Reed and the Velvets"]
So if Tobler's 1971/72 interview is published at all, it most likely is in another publication; note that in his 1973 book Trevena thanks first of all "John Tobler at Zigzag" [!].

Tobler's pieces were first of all published in Zigzag, only after 1972.Oct some started to appear in Let It Rock [UK, 1972-1975]
For Tobler writing in Zigzag seems to have been a hobby next to his fulltime [?] job at the IT department of a bank. At Zigzag he also did advertising, meaning mostly contacting record labels, so he sure had very good contacts there. Therefore if his interview wasn't published, it could be that he
--gave/sold a copy of his tape to Reed's label and/or management, who then later might have send it around as a sort of promo material
--gave a copy to other music writers, with whom he was in good contact and may be exchanged more info/tapes/etc. with
The full [?] interview was available at bootblogger-lyoko.blogspot.com/2011/05/lou-reed-interview-with-john-h-tobler.html
A copy is since 2022.Feb.16 available at doomandgloomfromthetomb.tumblr.com/post/676357233843568640/lou-reed-zigzag-magazine-conversation-with-john
Only on tracknr.01 "The Pickwick years and the Velvet Underground" [6:49] Reed speaks about his PW years:
Tobler: I'd be much more interested in you being a songwriter in a hit factory...
Reed: You mean when as I was working as a songwriter?
Tobler: Just at Pickwick right?
Reed [sounding surprised]: Yeah, right, right...
Tobler: Eh...
Reed:
We just churned songs out. That's all... [explaining the operation of Pickwick*]
*making rip-off albums, but
nothing about "locked in a room", "ten... ten... songs", nor "down into the studio"
PS: John Tobler has recently sold his own record label Road Goes on Forever (RGF), but the rgfrecords.co.uk website is still working and maybe he can still be contacted through it
