I also solder all parts in but use Sockets for the ICs. This is have I built the TGSL using Silverdog's PCB.
The BEST info is concise form is Dan Bower's TGSL 101.pdf documents. Find, download and study.
First is the TX Oscillator MUST run. Pull all ICs, except U108 (the 7808 regulator) and trouble shoot the oscillator (section 1 of the TGSL101 schematic). You may have wrong values components or have them mis-wired.
After Oscillator is running at 14.5kHz the install the clock divider. This drives the DC-DC boost converter to get the -5V.
Now continue installing ICs from RX through to audio ensuring each stage works.
