The MJE340 was driven by a 2N1613 from another board (not included) which is a general purpose 1/2 to 3 watt transitor All parts for the RF deck are included except: two 6LQ6 tubes, 4PDT, 12 vdc, T/R relay and the tank circuit (coil and variable capacitors). This Mackay Marine linear amplifier seems to be in very good condition. Missing top and bottom covers, 2 knobs and 4CX250 driver. Will produce legal limit with a pair of 3-500Z's (not included). 10 channels completely preset and auto-tuned as operator makes selection. Scientific Radio Systems RF decks for the SR-210 / SR-240 Series of Transmitter. This deck was designed to use two 6LQ6 sweep tubes (not included) driven by an MJE340. These complete decks were ready for insertion into the 3' standard rack. Will produce legal limit with 4PR-1000A (included). Add capacity / inductance to get down to 10 meters or decrease capacity / coils to get up to 6 meters. This was the beginning of the assembly process for building a 100 watt, 1.6 to 30 MHz, 6 channel crystal controlled transceiver. Scientific Radio Systems SR-204 Front Panel & Chassis Frame.
Minutes after the parts were delivered I was busy assembling the kits.
There is something magical about glowing bottles and high voltages producing lots of RF....
Below are the amplifiers in no particular order I have at the moment with a few comments on them.
Below you can see the 3 kits for the SB-200 assembled.
