Can someone please help me by identifying these three components and telling me what alternatives there are for them.
Can't seem to find them in stock anywhere.
I think they are as follows....1capacitor
2varistor
3gas absorber tube,,,Thanks in advance

The first one is a "Class X2" suppression capacitor, 0.1uF 250V AC.
Similar to this, but you need one with an appropriate lead spacing:

The second is a "Zenamic" style transient voltage suppressor (VDR), V14471U is a Panasonic ERZV14D471 which is rated 300V AC 175 Joule

This should be a suitable equivalent:

No idea on the third, sorry..

Hi rjenkinsgb,,,thank you so much for your knowledge.
You have no idea how hard it was to get this information.
You are surely a man who knows what he's doing.
I thank you sir

I've no idea what the third one is either. What is the board doing? The more information you can supply the more likely someone here can identify it.

Going from the ID next to it, DSA; possibly a miniature gas discharge type surge protector??

DSA-A | Surge Absorber for power line | Mitsubishi Materials Corporation Electronic Components Division

Mitsubishi Materials Corporation Electronic Components Division's 'DSA-A' is a surge absorber for power lines.

Paraffin heater mike

So mike,I cleaned out the combustion chamber of this paraffin heater in the old shed which isn't too warm.
I'm assuming,condension got on the PCB.
I brought the heater to the house and fired it up.
It ran ok for 20 minutes then just stopped.
No power even at digital display.
There are two 5 amp glass fuses on PCB.
Both in good condition.
Power go's in and out of the first one.
No power reaches the second one.
The box capacitor,three varistors and the DSA 1
are the only things between the two fuses.
Thanks for looking

Hi rjenkinsgb,that capacitor is coming up at 275 volts AC,and mine is 250 volt ac.
Does that make any difference??
Thanks

Higher is better!

Thanks for that
