TDA7338 FM stereo decoder circuit design

The pilot detector output is designed as an open collector output, therefore an external pull up resistor is needed. To force the decoder to `MONO` Pin 19 has to be clamped to a voltage below 0. 8V. visit page.

7 tube 20 watt amplifier

This is a 7 tube 20 watt amplifier that must be used in conjunction with a pre amplifier having volume an tone controls. For this, I recommend this 6 tube pre-amp. With this amplifier you may use 6BQ5 output tubes. A 5U4-G rectifier is used so that the power supply will have plenty of pep to run the amp. This amplifier is basically a Magnovox amp visit page.
