[QUOTE="marantz123, post: 854920, member: 16849"] Found my notes on this. The Hunts capacitors are 100nF (0.1uF) 400v rating, and correct...its one across the secondary AC and the other across the rectified DC, in parallel with the 5000uF 55v Elko/ROE cap ( Elko RAU 2A). The lamps in the display are 6v ,1watt festoon-type, 30mm length x 7mm diameter. Trailer lamps fit here perfectly, just have to check the voltage...never got to do this fix though. Some useless info.....Serial no. of the unit I had was 2412. Model TRS111M. The speakers were labelled as "TL111L Supersonic 15 Ohm". Transistor line-up...BC143/ 142/ 145/ 116, metal can types (TO3/5) and then BC148A / 149B/ 149C. The power output transistors 2x BD116 TO3 packages, and 2 others I couldnt see. On the tuner board, possibly Germainiums here...AF178/ 124 /125. 3x 8A130 diodes. The bandspread control on my unit wasnt connected to anythng. Hopefully ur unit just needs a recap and the general cleanup. Be very careful.....the painted text on the tuner display is very flaky and comes off easily. [/QUOTE]
