No mention of 120vac in specs nor channel separation. I would stick with the ST-70
and back to original.
If you want improved, upgraded sound, might check out SE-70, 3rd modification by
Pro Musica from Champaign (not Chicago). Even the second addition is quite good.

Comes in 120v
Have one since the summer. Mike has heard it
Features
Pure hand-made, the whole machine is welded with scaffolding.
Use a square power transformer specially developed for this machine.
The output transformer uses two high quality wideband EI output transformers.
The voltage amplification and boost stage uses a 6SN7 for power supply filtering.
The voltage amplification stage and the push stage use two pairs of 6SL7 and 6SN7 tubes, respectively.
The rear stage uses four KT88/6550/EL34 tubes for class AB single-ended power amplification.
Triode and ultra-linear selection are available.
External independent BIAS-ADJ current display header.
External EL34/KT88 tube selection function, easy to replace different types of tubes, adding endless fun.
Infrared full-featured remote control.
Use thick silver plated signal leads.
With pure post-level function, it can be connected to independent preamplifier signal input.
Power on mute delay function (about 30 seconds).
Select Japanese ALPS high-end motor potentiometer.
Easy-to-install plug-in tube shield.
