How to put a clock in a Arcam delta 70.2?
Whilst fitting the new clock, I would be tempted to take a look at the Audio board power supply, you will see a really nice discrete regulated supply for the Analogue audio stages, But 78/7905 regs are being used for the TDA1541A core supply these are a prime target for a some LM317/LM337 (Z201+Z204) and will allow for a more stable supply for the core, Beware these will not be a drop in replacement you’ll need a resistor net to set the ADJ pin of the reg, a 270 ohm of the output pin with a 820ohm down the 0V and the ADJ pin conected in between, configured as per widely avaliable datasheet on these devices would suffice.
