I have had several fails on those cheap n nasty Chinese 1 and 2 stage IF pocket radios. Then, when they do go they sound awful.
First radio I made was a Electron-Coupled TRF: EF39 plus 6J5 and 6V6 o/p. Used to squeal if you tried to wind up the volume to max.
I wouldn't class that as a fail, because it worked as soon as the HT came up for the first time.
It was a rats nest underneath the chassis. I was surprised it worked as well as it did.
I don't know Forum member Heatercathodeshort made his 'schoolboy' style radio work so well with the same line-up of devices. Even when I tidied up the underside of the chassis it never worked as well.
