Phone in the new house, was purchased on EBay for $15.
This one had a
sticker attached that said "6 long rings to report a forest fire"
Here's a shot of the
new garage Leich phone. Note the used
service panel with a 66 Block.
The service panel is used as a "data closet"
for distribution of telephone, internet and TV signals throughout the garage
and MIL apt.
The white box under the phone is a doorbell that chimes briefly when the
main gate opens.

Note the small voltmeter used to monitor the DC Talk Voltage.
When you speak, the needle moves rapidly like a VU meter!
Note the white slip of paper in the top right. It lists the "ring signal"
for each person on the system.

Disassembly and a thorough cleaning are often all that these phones need to
be ready for use.
Electric Company manufactured early magneto and dial equipment for the telephone
industry in the 1930s and 1940s. Robustly made, these phones function as an intercom
between the eight main buildings at Valhalla.

These phones are very robust and versatile and can be configured in
several different ways to meet the needs of rural telephone systems,
railroads or mines. This system is wired in a "common battery" configuration where all of
the phones are on the same party line and when you turn the magneto crank,
they all ring. Its very helpful in communicating "dinnertime"
We are currently writing a pamphlet on how to restore the Leich 901
Magneto Telephone and assemble a system using two or more phones of this
type. Also included are specific instructions on how to
connect these phones together to make a very interesting intercom

This is essentially the same basic telephone that
Alexander Graham Bell invented in 1876. A DC talk battery in series
with a carbon button full of carbon granules and on the other end, a permanent magnet with
a winding that caused a diaphragm to make air waves. The varying talk
current can even be observed on the small voltmeter in the photo at
right. When someone speaks into the telephone, the meter needle moves
quickly in response to the words spoken.

The Leich 901 phone converts between desktop and wall mounting by virtue of
the ingenious way the handset cradle is designed.
Utility building workshop phone.
Three old12 V car batteries places at the "ends" of the system provide "talk power"
The magneto crank
generates 75-100 Volts AC to ring all of the phones in the system
We chose to use the the
classic Bell System "66 Block" as
an interconnect point.
Available from telco supply houses, these are easy, handy and make nice solid connections
using a special "punch down" tool.
Here's a shot of two more "66 Blocks" in the
house basement data closet.
66 Blocks are used here to distribute stereo audio, gate control and
through the house.
Note the voltmeter in the upper RH corner to monitor the
DC talk voltage on the system.

Note the 12 Volt "Talk Battery"
and also the "old bones" found under the
pioneer house. The system's 1930
designers intended to have a talk battery at each phone when used in rural
areas but we've found that using several old car batteries strategically
placed at various nodes of the system provides enough DC to operate all
phones, even the one at the gate,
500 Ft from the battery.
The old car batteries are down to about
8 volts and this voltage is probably what Leich designed for. At any rate
8VDC provides good volume and clear communication.
Here's a Kellogg Switchboard Co magneto phone from the
same 1930's time period.

Heck, there's even one in the Picnic Shed.
All wiring is underground using commercial "direct

This is great to call the main house when the picnic runs out of hot dogs.

Here's a Leich 901 in the basement office.
The sticker on the front reads: WARNING This telephone
subject to monitoring. Do not discuss classified. This unit evidently came
from a military base.
Lower Garage Phone
Note the old car battery on the left supplying about 8 Volts for the DC "Talk Voltage".
Batteries are the preferred way to power the talk voltage due to the "pure
DC" output of a battery versus an AC-Line power supply that could introduce
hum into the system.
The car batteries require little maintenance. We connect
a charger once a year to "top-off" the batteries. The general rule
of thumb on this system is to have an additional battery for each 100 ft of
