PM-200 Replacement Power Supply Module for the Heathkit SB-200/SB-201 The PM-200 is a complete replacement power supply module for the Heathkit SB-200/SB-201. It features new modern 180uF 450VDC electrolytic capcitors, 1000 PIV 3A diodes, new 82K 3W bleeder resistors, upgraded meter shunt resistors and a precision high voltage meter divider string.          Our Price $90.00 - Shipped in the USA - International shipping cost to be added.

PW-200 Power Supply Module & Soft-Start Combo for the Heathkit SB-200/SB-201 The PW-200 is a combination of the PM-200 replacement power supply module and the SS-201 soft-start module for the Heathkit SB-200/SB-201.  The price for the PW-200 is less expensive than purchasing the PM-200 and SS-201 separately. The kit includes power resistors for 220VAC mains operation.  If the amp is operated on 110VAC mains, the resistors must be changed to 10-ohm 10-watt.  These may be ordered on the website (RES-121).             Our Price $110.00 - Shipped in the USA - International shipping cost to be added.

FM-200 Replacement Fan & Motor for the Heathkit SB-200/SB-201 The FM-200 is a direct replacement fan and motor for the Heathkit SB-200/SB-201.  The motor features "oilite" bearings for quiet operation.  The motor is a little larger than the original so it moves a bit more air than the original fan.  This new fan and motor combination is the best defense against tube failure due to overheating.  NOTE:  Although the fan is stamped to tight tolerances, it is advisable to balance the fan blade before final assembly.  See FANBALANCE document in DOWNLOADS section for details.            Our Price $50.00 - Shipped in the USA - International shipping cost to be added.

SK-201 Soft-Key for the Heathkit SB-200/SB-201 The SK-201 safely acts as an amplifier interface to your modern transceiver to the Heathkit SB-200 or SB-201. This unit is mounted inside the amplifier and transforms the negative 120VDC key closure to approximately 0.7VDC at 1.5mA.  Without it you run the risk of severly damaging the keying circuit in your transceiver.   Our Price $27.00 - Shipped in the USA - International shipping cost to be added.

SS-201 Soft-Start for the Heathkit SB-200/SB-201 The SS-201 limits inrush current during amplifier start-up by placing a small resistive load in series with the AC mains. The load is switched out of the circuit by the relays a few milliseconds later. The soft-start mounts inside the amplifier and safely limits inrush current to protect hard-to-find and costly-to-replace ON-OFF switches, tubes, filter capacitors and high voltage transformers. The kit includes power resistors for 220VAC mains operation.  If the amp is operated on 110VAC mains, the resistors must be changed to 10-ohm 10-watt.  These may be ordered on the website (RES-121).   Our Price $30.00 - Shipped in the USA - International shipping cost to be added.

RY-200 Replacement T/R Relay for the Heathkit SB-200/SB-201 The RY-200 is a replacement T/R relay for the Heathkit SB-200/SB-201. It is a 2PDT relay with a 120V coil.  A new mounting screw and rubber grommet is included.  Also included is a new 4.7K 5W R-18 replacement.  This resistor is included to replace the original R-18 (2K 7W).  This resistor must be changed due to a change in coil resistance of the relay from about 2.3K to 1.4K by the relay manufacturer.  This will allow the proper amount of operating bias to be applied to the tubes during transmit (~ -2VDC).                       Our Price $30.00 - Shipped in the USA - International shipping cost to be added.
