Goede morgen Maurice,

Thank you for your fast response.

Yes, ech4 tube is a rare tube but it can be easily find in auction site.

I've already bypass the rf stage, ussually using a long wire antenna at the grid input or top cap on ech4 tube, but still no reception or noise at all.

For your information, i've already fixed the 3 gang of the variable capacitor.

Warm regards,

Winstony
