Original Cassette was created by Philips Holland...1964! Portable battery recorder. Retail Price Range $ 99. Model EL3300 About 1965 improved AC bias...improved sound Philips EL3302 approx $ 110. The SONY TC 110 at approx $ 155 became a MASSIVE seller to all radio stations for interviews. Stations that even used the early EL3300 (also the TC 110 well into the 1980's !!) would use Electro-Voice microphone 635A. The mic approx $100 in 1964.
Hi Jeremiah. The cassette looks like a studio copy, I can't say if the speed is perfect or not, really. But i'll leave the upload as it is. Thank you anyway.
