Business Phone Repair Parts
 

HANDSET PARTS....

Electret Handset Transmitters:
 
EMS-93L - Standard Gain - Silver Metal Front - Saltshaker Holes: $4.69

The EMS-93L is the same shape as a Carbon Transmitter with the two rings on the back, but the front is Silver instead of Black or Gray plastic with big holes.
 
NOTE: If you use a Carbon transmitter on a phone that needs an Electret transmitter you'll get high side tone and distortion. If you use a Electret transmitter on a phone that needs a Carbon transmitter, you'll get NO transmit.
 
 
EMS-93 - Same as EMS-93L but Loud Gain: $4.69
 

The wires need to be soldered to these tiny transmitters:

EM1 - Standard Gain Pencil Eraser Sized (3/8" by 3/8"): $3.29
 
EM3 - Loud Gain Pencil Eraser Sized (3/8" by 3/8"): $2.99
 
EM2 - Very Loud Gain Pencil Eraser Sized (3/8" by 3/8"): $2.99
 
 
Electret Cancellator for G-Style Handsets (Replaces Cap) - Black: $26.95
 
This is a screw-on noise cancelling transmitter for a G-Style handset (like a Confidencer). It sticks out about an inch replacing the original transmitter cap, with the two rings in the back to hit the metal contacts in a standard transmitter cup.
 

NOTE:  We can put a noise cancelling electret transmitter in most but not all handsets, and can sell you one that you can try to put in your own handset (requires custom fitting and drilling to install port to the rear of the mic - more than most mere mortals can handle).

 

Static Electric Shocks Kill Electret Transmitters!

Are handsets going bad with a "no transmit" complaint, especially in the winter? It's probably because of static electricity in the office.

If you feel a shock when touching a metal file cabinet or doorknob there's static electricity. The electric shock travels from the user's lip to the transmitter in the handset, which if it's electret has a small transistor in it that can't handle that high voltage (low current) shock.

The sane thing to do would be to humidify the office, or treat the carpet with anti-static stuff.

The cheapest DIY fix is to mix a 50/50 mixture of Downey Fabric Softener and Water in a plant sprayer with a nice big trigger, and spray the carpet, chairs, etc. It lasts about 2 months, and stops problems with computers as well as phones.

 
Carbon Transmitters:
 
T1 (T100) Standard High Quality Carbon Transmitter: $4.89

Two rings on back for the metal contacts in a standard Transmitter Cup

T2 Vandal Resistant (Metal Grill) Standard High Quality Carbon Transmitter: $6.29

Two rings on back for the metal contacts in a standard Transmitter Cup

 
EMS-94 Electronic Carbon Replacement with High Quality Sound:  $14.95.

Includes the transmitter cup (remove the old one).

Fixes packed carbon mics so they never go bad, like on the ITT-701

 

Carbon Cancellator for G-Style Handsets (Replaces Cap) - Black, Ash & Ivory: $32.95

This is a screw-on noise cancelling transmitter for a G-Style handset (like a Confidencer). It sticks out about an inch replacing the original transmitter cap, with the two rings in the back to hit the metal contacts in a standard transmitter cup.

It does not use carbon granules. It's an electronic replacement for a carbon transmitter.
 

NOTE:  We can put a noise cancelling carbon transmitter in most but not all handsets, and can sell you one that you can try to put in your own handset (requires custom fitting and drilling to install port to the rear of the mic - more than most mere mortals can handle).

 

Dynamic Transmitters:
A Dynamic Transmitter is actually a receiver cartridge being used as a transmitter.
Usually the elements will be the same size for transmit and receive (2 big or
2 small cartridges).
 
Important: Cut one side of the Varistor to use a receiver as a transmitter (if there is a varistor).
 
 
MT91 - Small Dynamic Transmitter - 1 3/8" diameter: $4.39
 
DR-1 - Full Size Dynamic Receiver / Transmitter - 1 3/4" diameter:: $2.99
 
 
Transmitter Spacer: $1.59
 
To use the small size (1 3/8" diameter) receiver as a transmitter in handset requiring a large (1 3/4") transmitter.

Dynamic Receivers:
Work in 1A2, 2500 Sets, many K & G Style Handsets and more!


DR7 - Small Dynamic Receiver (No Varistor) - 1 3/8" diameter: $3.99


DR-1
- Full Size Dynamic Receiver (With Varistor) - 1 3/4" diameter:: $2.99
 
Varistor for Handset Receiver: $ .60

Put it across the receiver leads to stop loud clicks in the ear!.

MEMORY BATTERIES

Are you sending circuit boards in for a $75 repair just because it needs a $10-$15 Battery?

Lots of phone systems are old enough to have worn out the memory batteries. If it won't hold the program...REPLACE THE BATTERY!

We have them for most systems. Call us with the type of system, the way the battery mounts, if it has pins, the model number (Nicad, Lithium or whatever), type, voltage and mah (capacity) of the battery.

Nicad batteries are recharged by the circuit board. Lithium batteries aren't charged - they just wear down over time. Don't mix up the type of battery!

 

51A LAMPS

Bag of 10 @ $7.95.

Take-outs. All lamps tested good. Use for 1A2.
