and (especially) if anyone in the southern half of the UK has one to sell.
Steve - I'm very interested in your LED modification to your 54. Are these relatively easy to construct? Also I assume this light source works well with modern VC papers and filters. Are you able to expand a little, please?
It's documented in a couple of threads here. Do a asearch for LED enlarger. If I get time I will find them and put links in this thread.
Basically I used the PCB from an LED stage light which has 153 LEDs, 51 each of red, green and blue. All three are used for focusing then the blue and green are used in varying proportions to get the change of grade. A range of about 1 to 3, possibly 3.5 is possible. Others have managed higher grades by using UV LEDs but I haven't gone that far.
EDIT: That was easier than I thought!

From my research so far it seems wise to avoid cold cathode heads (difficulties with multigrade), DeVere as a make (complicated and too much to go wrong) and Ilford multigrade heads (unreliable and expensive).
