Tapehead
Just to illustrate the point about the ridiculous money asked by some sellers
USD 594 (£475) for a "sealed NOS" copy of Sgt Pepper's 7.5 Its 4tr tape (on Ampex tape stock - I would steer clear of this!!!)
OR
This - a 15 IPS 2 track copy of a production master for less money
Wow - I think i have this and a few other Beatles tapes.
