Heathkit Drake Dentron Parts
Dentron Plate Choke and Parasitic Suppressor Kit
We also have OEM carbon composition resistors if you want to rebuild your OEM suppressors. This is our RFC245 plate choke with our TPS4 suppressor installed in a Dentron Clipperton L amplifier. The suppressor and choke bundle with hardware, USA shipped, is $100.

Heathkit SB200 Heathkit SB220 Plate Choke
We also have OEM carbon composition resistors if you want to rebuild your OEM suppressors, and we offer a superior assembled parasitic suppressor!
OEM original quality, exact electrical copy. Mounts the same as the original Heathkit 45-61 choke
OEM Style PN 45-61 Heathkit Plate Choke on ceramic form

$49 shipped. Unlimited inventory, although lower terminal design varies. The copper snap ring on right actually has better RF characteristics.
Antenna Relays
Link SB-200 SB221 SB201 SB-220 120Vdc 110Vdc 3PDT DPDT Antenna Relay
This 110Vdc 120Vdc DPDT or 3PDT relay is compatible with Collins, Heathkit, and other high voltage dc coil relays. Unlike other systems this relay is properly sequenced.
Link to Relay Buffer Board (Soft Key)
This relay buffer is better and more reliable than other relay buffers. It has a more normal trigger threshold voltage for additional reliability. This system is compatible with any amplifier, including the Collins 30L-1, SB220, and SB200 amplifiers.
Power Supply Components
We sell power supply and other components. Our rectifier board is made to commercial high voltage standards. Unlike other boards, we have at least 100 mils spacing per 1000 volts between traces. We are especially careful in our designs with spacing and layout of metering and other sensitive traces.
Since our SB220rect rectifier board has full modern meter arc-fault protection, our SB220 filter and rectifier board bundle omits these parts.
If you have the OEM rectifier, you will need the clamp parts. You will need a more populated board.
If you have the Harbach rectifier board you only need the 10-ohm surge resistor, but this requires adding a new 3kV feed wire to route the 10 ohm surge resistor in line. No matter what anyone claims, a low resistance fractional ohm resistor or any resistor in the negative rail is not a functional fuse or glitch resistor.
Link to SB220 SB221 Power Supply Board
This direct fit power supply board improves airflow and reliability of SB220 filter capacitors. It also mounts in many other amplifiers.
Filter Capacitor Board connections
Link Universal Step Start Board SB200 SB220 30L-1
This board directly fits the SB200, SB220, and Collins 30L-1 amplifiers when configured for 120Vdc operation
Universal Step Start configured for 12Vdc systems.
