For Sale: Heathkit GP-11 Power Supply
Here is a fine old Heathkit vibrator Power Supply that will develop B plus
of 250V DC at 100 mA.
Perfect for Heathkit "BENTON HARBOR Lunch Box" transceivers, and other tube
amateur radio gear.

The GP-11 has the convenient feature of being suitable for both 6 and 12
volt inputs. Output is 250V at 100mA.

The Heathkit GP-11 was a modular vibrator power supply, that it was
available in kit form. It was also of the last generation of DC-DC vibrator
power supplies.
They were being made in the early 1960s era, and unlike Heatkit's earlier
VP-1-12 and VP-1-6 vibrator power supplies, the GP-11 uses silicon
rectifiers.

Heathkit's vibrator power supplies were designed to be used with their
amateur band and CB transceiver kits, but of course were also suitable for
many other tube applications.
 By 1961, the silicon rectifier technology was well established, and it was
more efficient to use solid state diodes than a tube rectifier. The power
supply also runs cooler which is all to the good. While a synchronous
vibrator would provide the same efficiency as using silicon diodes, one
loses the convenience of a non polarised input, unless a reversible type is
used.
The power supply was working when tested.  With this age it cannot be
guaranteed. So the price is set accordingly low and you can enjoy this
classic supply with your radio equipment!
