The Valve Kit (6J1) - UK Vintage Radio Repair and Restoration Discussion Forum

Radio Tech · 3rd Jul 2014, 9:13 pm

Hello folks

Has anyone ever built the 6J1 valve radio? If they have what coil did they use and what size was the former. The reason I ask is that I came across the information on this little set but it just does not mention anything about the coil except for the number of turns no data on the wire size at all, I am going to have a go at building it.

Regard

Ken

If this is the Chinese one you need to wind the coils on an AA battery, each turn spaced from the next by 0.5mm. I think it is 0.8mm wire.
I might be a little inaccurate about the wire size, mine is 215 miles away!

Thanks Richard,

I will have a go with dimensions you say, I didn't know there was a Chinese version, I just naturally assumed the design was German, but anyway many thanks.

regards

Ken

Hi Ken,

I'm now not sure that we are taking about the same single-valve radio. Mine is a kit based on a 1A2 valve I bought from a Chinese mail-order house......

The 'German' example seems to have a ready-made coil and seems to do short wave only.
Not sure what there is on there at present.
That particulr example has a LM386 IC to boost the audio to speaker strength.
The kit instructions say the 6J1 is the EF95.
I have no idea where you would get the kit from, but the price seems to be around 50 Euros.
