Dear all,
Im looking for some advice regarding my hacker mini herald. Was working but was very hissy and poor reception. Some capacitors had been changed in the amp section before I purchased. The remaining capacitors were all out of value so I recapped. When it turns on nothing, now completely dead. I double checked my work, capacitor polarity etc against schematic and all ok. One of the af117s had also been changed for an equivalent before purchasing. I've checked and changed the remaining 117s with Russian soviet equivalents still nothing. Checked all general wiring and reflowed the solder connections. Next stop I'll have a poke with the audio probe, but just looking for any further assistance.
Many thanks
