Will a Toroidal fit in the Chassis. Plus I thought the 818 or any Onker past the 7 series was THX certified. That modification would make it more Integra.
When I got my Tascam PA-R200. Was super stoked 7.2 THX/Toroidal. Later found out was actually a Onkyo/Integra 30.4. Direct clone manual and all Just different faceplates. Made for Teac/Tascam in the Integra factory. Very short run 2013/2014. My M80 V.4 got it really warm.
Funny they've just released a tape deck {Tascam} nostalgia everywhere Vinyl and tapes on a come back.
