Default Re: HMV Thorn 1500 Low audio and no video!

Yes they could have easily provided protection but I suppose every penny pinched was a penny saved...
I think usually the transistors went open circuit I can remember having to change all of them in most cases . Very occasionally some would survive probably "protected" by one going short and reducing the LT voltage...

The firm I worked for had a lot of 1500s and ran them into the ground. The boss could see the end of black and white, certainly as far as rental was concerned so he didn't invest in any new sets, the old single standard hybrids were kept going with Unitra Tubes and Pinnacle valves . They still had lots out on rental when I left towards the end of 1980.
