Peter,
To be honest with you I'd have to say I don't know - most of my use has been in using it for voiceover sessions, I've used 90 and 124 tapes in it without any problems, and I wasn't aware of any issues with the model - so I'll have to defer to Beechwood's superior knowledge.
I've some photos somewhere I can mail you if interested.

Wavy grooves go thru a RigB 540ML on an SL1500C. Digits stream from a cheapie CDP and a Sonos, into a Yamaha 803D driving Kralk Audio little 'uns. I used to have a Linn but I'm better now.
