Mains dropper on a DAC90a

[tiv48]

i did use plaster of paris once but thats because a section of th dropper had gone open circuit and i had to resort to scraping the covering off till i found the break then unwound one turn and twisted the ends together next covered with plaster cant say how long it lasted told the owner it was tep until a replacment dropper could be got , he then moved and we never saw it again so if anyone comes across a thorn 1400 with a white dropper section youl know why.i know it was a bodge but he was desperate for the set
