Power transformers for sale,
P37 to P103, March 2011.
How to understand the tables below:-
Power transformers are numbered P37 to P103.
VA = Maximum continuous Input current in amps rms x Input Vrms.
pcs = number of pieces in stock.
HT = High Tension Vrms of highest voltage of secondaries.
Where just one voltage is given, it means there is a single untapped winding
with the voltage show.
Where a HT winding has one of more taps the tap voltages are given after
the maximum voltage.
Where a HT winding has a CT, the winding is given as Vrms-0-Vrms.
The HT winding current is the equivalent winding rms current based on
estimated VAout of the HT winding / HT voltage, Vrms.
B+ = Vdc produced under medium load conditions and is calculated
as HT Vrms x 1.35. Vdc is given for taps on windings.
It is assumed diodes will all be silicon and directly charge a capacitor
with reactance at twice mains frequency < 1/50 of the amp load,
ie, Vdc / Idc.
Ib = dc output current from capacitor amp load.
Where TWO Ib are stated for a transformer it means there are
TWO HT windings, for anode and screen/input stage supply.
Bias Vrms = voltage supply for generating grid bias for output tubes etc.
Bias Irms = maximum bias current from bias winding. In practice,
bias currents should be well below the mA shown.
The possible Vdc and Idc for bias supplies may vary depending on
the type of rectifier, bridge or doubler etc, so Vdc&Idc are not given.
Fils Vrms = filament heater winding voltage.
Where more than one filament winding exists, it shows say 6.3V x 2 or more.
Fils IArms = filament heater winding current maximum.

Where more than one filament winding exists, it shows say
4A x 2 or more.

Core type = type of cores used. These are mostly double 00 C-cores
but some have a single 0 C-core. Some PT have E&I laminations
and a few are potted in a soldered hermetically sealed with tar
or epoxy potting compound while a few are sealed in a pot
while immersed in transformer oil.

Price is in Australian Dollars at time of purchase.
