Hello Friends! I have recently received a very nice old Philips Allegro 890A. It is the Czech-licensed version, with the A-roehren. I have several questions before I begin restoration:

1) I want to remove the radio from the cabinet so the chassis can be carefully cleaned. It is quite dirty. However, I do not want to try disassembling the Monoknpof before removing the chassis. What is the best way to remove the chassis?
2) I also want to remove the dial scale assembly. The Glas-skala is loose, it appears that the cement holding it in place has failed over the years. The glas-skala is not broken, just loose.
3) The netzschalter control on the side of the radio has a switch on the back, which has come off. The three tabs holding the switch assembly in place have been slightly bent, allowing the Bakelite switch housing to come off. I have found the little fiber plate which makes up the switch element, and I wish to repair it. Can someone assist me in getting this switch back together?
4) There is no power cable. However, just behind the netz-trafo, there is a fiber plate with a number of pins extending out; this is just above the input voltage selector. Does anyone know if there exists a suitable "netz-plug" for these pins?
5) The skala-bulbs are 4V, but what size thread do they have? E10? I will need to acquire a full set of bulbs, perhaps 10 to have some spares.

I have tested all the tubes and they are OK, even the AM1 eye-tube has usable glow!

I have been sent the entire 33-page Service Manual for the radio, by a friend in Germany. The manual is in Dutch and I have no means to have it translated

If someone can help me with this project, I would be very grateful. My direct e-mail address is ac1y@nc.rr.com

Thanks very much!
