Thanks guys!

Hello peeps! Thanks to a member here, who knows who they are ;) I was kindly sent two transformers that were for a small push pull transistor amplifier. The driver one was the most suitable as the sound from the output one was noticeably muffled, teach saying because it was "not gapped core" (I will...

Re: Hey there, I'm Ami!

Refreshing to see a girl on any of the forums, welcome Ami enjoy your time here. Thanks Andy and all! People have already been so helpful, one day I hope to reciprocate, I find it odd that in my age group engineering interests is maybe 25% to 75% girls to boys but I've only noticed a few ladies on ...

If someone could find a transformer I could do payment in kind (with electronique junque that is, valves etc. :oops: ) pending apro from Mum, of course, or just buy it outright if the price wasn't t...

Re: information needed about low power amp topology

Hello peeps! Can you give any details on this "unobtainum" article ? It was called the "sliding junior" by Sir Douglas Hall. Published by the R&EC magazine in June 1973, I printed out the article at school, I think from the American radio history website. I'm out enjoying the sunshine at the moment,...

Re: information needed about low power amp topology

I just did a Google search for "simple audio amplifier circuit" and got lots of hits. :roll: Thanks Mike you're a lamb for trying.
