1969 class A amplifier. While JLH 1969 is a simple design, it is still one of the best transistor amplifier.

This incarnation features :

1. Double-sided , thick copper PCB. Most of the JLH 1969 boards in the market are single-sided. This one is doubled-sided so the copper pad durability is greatly enhanced by plated-through hole ( PTH) process.

2. Hermetically sealed metal casing transistors used on both small signal and power stage.

3. High quality electrolytic capacitors.

4. High quality solder with silver content is used in soldering.

5. ERO film capacitors for audio coupling.

6. Thick & heavy aluminum plates already mounted on the board( as in the pictures) for easy to interface with heatsink.
