TR37: 2SC945, TR36 and TR38: both 2SA1282, D76: 5.1-Volt 1/2-Watt zener, and D77, a KB362 "two-junction", or "temp sensor" diode. A series string of three generic 1N4148 will replace the single KB362. A single 1N4148 in that spot could very well get you the "yellow light" syndrome all by itself. A single one won't work to replace D77. These parts are all at the front corner of the EPT3600 board near the speaker.
And CBTricks.com has this one under the "DX-11B" model number. Close enough.
