Cliff -
Just saw you post. As I remember, the original control board was the “ceramic substrate” version used in EC1001 model. Most common problem is hairline cracks of traces, as underlying ceramic substrate cracks.
I have a refurbished Weller DEC1001 station — that I am finishing for the auction site.
Let me know, I have other “dual handpiece” Weller stations.
Your “ideal” solution would be the Silver Series WSL2 or WS-161 station. It supports your earlier DEC1001 handpieces (EC-1201A, EC1302B) and the new 80 watt WSP80 iron.
Peggy Grady in Tempe, AZ is selling NOS Weller WSL2 base unit (equivalent to WS-161 model).
I picked one up (I prefer LED instead of LCD), and it arrived in original Weller box !
