Hi , I'm in the process of restoring the Fada 60 ,and looking at replacing the 6 Caps ,3x .5uf, 3x 1.0uf. There is one large 1.0uf can and 2 small 1.0uf can , thinking maybe difference is in voltage rating? What should I use to replace these caps , just orange dips or electrolytes?
The white metal frame was deteriorated so have manufactured it from aluminum, now starting to put things back together.
Thanks for now, Martin..................

Can you point out the specific caps you are referring to: http://www.nostalgiaair.org/PagesByModel/499/M0005499.pdf There are more than six caps - and I don't readily find the values you mention.
The schematic seems to show the voltage rating for the caps. Are the caps in question original to the set or replacements? Most times, caps have their rating/value printed on them.
You can any type of cap, film or electrolytic. But in the higher values, film caps may be physically too large.

this is the correct wiring diagram for the R60

Oh, OK - Model R60, not Model 60. This is a battery-powered TRF set, using '01As. Any of the caps can be replaced with rating 160-V or higher.

Doug , is it appropriate to use 2, 1uf caps in series for the .5 uf caps as it appears .5 uf 160 v caps are not common. or would it change the circuit too much by using 1uf for the .5uf , I haven't worked on any TRF circuits before.
thanks Martin............

I think any of those options would be fine. My interpretation of the schematic is that those caps just supply stability and regulation to the battery voltages. Assuming you use a battery eliminator, those caps aren't quite as critical - but still helpful.
