Default Re: Rather grim Thorn 1400 - Marconiphone 4649

Quite a challenging project you have got here.
On 1400's and early 1500's there was a must do modification on the width chain to prevent a fire.
The width control changed to 2.2Meg with the feed resistor increased to 680K.
many years ago I had a really good 1400 go up in flames because of this.
