I've tracked down the former Durst regional rep who used to repair Durst pro grade enlargers eg: Multigraph, Durst 1200 etc in the UK. His name is Roger Francis, he lives in St Albans, Herts. He has just done a wonderful job on my Multigraph. ( repaired circuit board, calibrated filters, checked probe etc)
He is prepared to travel, ( within reason) and and he's still servicing and repairing these machines to Durst standards. Also supplies spare parts, which are becoming harder to find. In other words, a handy man to know. You can reach him on :
rogfrancis@hotmail.com
I'm sure he can also offer advice online too. However, be prepared to pay him for his labour. He is retired, but still wants to earn a living. His rates are very reasonable. He has travelled to clients in Europe in the past, as long as airfares and a little bit of extra time are covered.
Best wishes,
Alan.
