I recently posted a question asking for advice about a replacement light source for a cold cathode head for an old Lines and Jones enlarger that I had ordered b ut had been broken in transit. The shop couldn't find a replacement as it's abou t 40 years old. They refunded my money and told me to keep it as they didn't wan t it back. Several people suggested an Aristo replacement and they had one almos t the same dimensions but it was going to be about $300.00 all in. Pete Andrews suggested a Mustek transparency adaptor, tracked one down and reserved it for me . It arrived today cost, #50.00 and after a couple of minutes with a hacksaw fit s perfectly well for my needs. The light source is even and bright, so LF b/w pr inting is alive and hopefully well in Yorkshire. Thanks Pete. Oh and it's going to cost me a beer as well.
