The tape winds on the take up spool oxide side out, so full track machine. There is a separate monitor head.
Speed is 7.5 & 3.75 ips. Other models in the series will have different speeds.
A switch on the rear selects the metering function.
The internal loudspeaker has an on/off switch.
Very similar to TR50 (lacking dial centre rear). There are a number of different superficially similar TR51 models.
It is portable only in the sense of transportable at a time when similar tape recorders were large consoles. It's very heavy with two stout handles. When the lid is closed it resembles a "flight case".
There are two main electronics chassis:
PSU & Audio amp: DH77 (or 6AT6) N78 U50
Record/Replay: This has EF40 x 2 and Z77 on a single anti-vibration mount with L77 EF91 N78 mounted directly.
Removal from "Rexine" style covered Wooden "Flight Case".
- Un-hitch the lid retaining bar and place unit upside down on a foam mat or cushion.
- Remove rear panel (knob pulls off) and remove meter switch extension shaft.
- Undo 4 screws on base.
- Lift box/cabinet off the chassis.
