Noob to tubes- Maco 200
- Thread starter dozerman

Only applies to a stable amplifier. And that's my main gripe about Maco's built-in driver stages. They oscillate and spew all manner of frequencies the radio has no idea about. Grounding the shield of the output coax and placing a Faraday shield between the driver and final tubes up topside goes a long way even if you don't take it any further than that.
