Oh, those dreaded ZTX500 series e-line transistors. Always went phuff at the drop of a hat.
One little trick with Speccys, to check the memory, enter the following command.
PRINT PEEK 23732+PEEK 23733*256
A 48k machine would reply with 65535, a 16k machine with 32767. From there, with a bit of extra peeking it was possible to identify which memory chip needed changing.
