Nak, Revox or Tandberg….but the Tand not all that reliable ( my opinion based on selling and servicing hundreds ….i know there are unicorns…. but let’s face it, NAK and Revox, the aint… Sonics on all 3 excellent. You got great advice on budgeting for a great tape tech to go thru your purchase.
Have fun, I have a 2 head Nak in the garage and greatly enjoy listening to tapes in made in the 70’s…. i guess, i am ancient…
