There are some very odd looking caps in this radio. I've never seen anything like them and I can't find examples of them on the internet. Hopefully someone can identify their type from the pictures.

Photos uploaded.

Some of those wax caps look to have been gnawed by a rodent or insect.

The pale blue ARTS&P label with G on it would tend to indicate 1940-1941, which is a decade before any model that I could find with that valve line-up, so this seems to be a real 'bitsa'.

What looks to be "2-64"on the power transformer could signify Feb 1964, in which case it is likely a replacement.

Thanks. I mentioned the G prefix being from 1940-41 in my original post. The power transformer can't be a replacement, as the original radio was battery powered. If you are right about the 2-64 marking it means the radio was converted to 240V sometime after Feb 1964

Chassis has holes for octal sockets or older.
So, it may have been a battery set, revamped in the 1960's with 9 pin miniature valves and power transformer under the chassis.
Still, a worthwhile project, as someone has previously gone to a lot of trouble.

Thanks Johnny,
the battery powered Fisk Radiola model 86Z, which I suspect it was originally, had the following valves: 1A7GT 1P5GT 1H5GT 1Q5GT.

I just found out the farm where the radio's original owner lived had mains power connected on 24/6/64. That supports the theory the power transformer was installed in 1964 or later.

That looks like a pretty conventional valve line up.
Should work nicely.
Replace all those horrible caps and resistors and with a bit of luck the rest will be ok.
It makes a nice little project to learn from.
As there is no originality to worry about you are free to modify at will if some section needs modifying.
Go for it.
Fred.

Thanks Fred.

Does anyone know what type of cap is in the red box in one of my pictures? I’ve never seen anything like it.

It's a 4 pF mica cap. Made by AWA.

Thanks Ian.

It really is a bitsa.

The transformer I am pretty sure is HMV.
The square Bakelite block is a pF cap.
Those brass clamped caps are Mica and virtually indestructible.
The white bellied tubular jobs are plunger type trimmers that date to the original manifestation like the brass Mica's. You loosen the nut & slide the plunger up, or down then re-lock.

One can see from the holes the change of sockets.

I would expect, as the gang and its coils are a factory matched set (coil set), too either be original, or from the donor set. This brings the warning of not touching Mica caps across coils. They are often unmarked and put there to bring the coil into spec. Caveat Actor applies.

It may have been flipped as the "doer" could not get it to work properly. Beware of the size of the filter caps: If too big they will strip the cathode of the rectifier.

It may have delayed AGC as both 6N8 (Pentode) and 6BD7 (Triode) have two diode plates.

BC is Broadcast Band which is AM not FM.

Good info thanks Marc.

So are those white bellied tubes trimming capacitors or trimming inductors?

I've ordered replacement caps of the same value as the originals. Whether they are the correct size I don't know, because I don't have a schematic. I'm relying on the person who did the conversion to have got it right. 32μF seems about right though.

Just to clarify the conversion of this set- the original owner had it converted from battery to 240V operation when mains power was connected to their farm in Wagin WA in 1964. As far as I'm aware it worked well after the conversion.

The tubular capacitors are only that: Capacitors.

I would pay to see if you can marry it to a circuit especially where caps have be treated as ratatouille.

If this has the original IF transformers. That may need some research into what their frequency is?

Can you please confirm the "white bellied tubular jobs" are trimming capacitors?

If the IF transformers are the originals they should be 455kHz, assuming I'm correct about it being a Model 86Z originally.
