Winner 120

On the "Winner" and "Portable" series the low voltage is a GB (Grid Bias) tap, not an actual LT (Low Tension filament) cell(s). Though some used with "All Dry" sets from 1939 (e.g. Portable 61) the LT would usually have been rechargeable Lead Acid 2V cell

Connection is by a socket at each end and flying leads with small plugs for + and - or various taps. None of this series use layer cells / "Biscuits", all use separate cells with connection wiring.

No Grid bias tap on this model

On most older HT packs there are taps for various screen grid or earlier stage voltages as this was cheaper than resistors which were only easily very low value wire wound or very high value "grid leak".

This pack has taps at 48, 60, 70 and 108V. See Vidor L5038 photo

The 80 off "B" cells are arranged as 8 x 10. Thus each column is 12V which explains tap locations.  There is also a version with taps on every column (12, 24, 36, 48, 60, 72, 84, 108 and 120) described as a Winner 120. The sockets are for split pin plugs approximately 1/8th inch (3.2 mm).
