Hacker Sovereign radio

[ppppenguin]

Hello and welcome to the forum. There are many low voltage adaptors available, but there are a plethora of voltages and connectors which can be very confusing. Most are now switchmode rather than linear. These may work OK but can give unacceptable background noise on the radio. I don't know which connector the Hacker uses but there are several concentric circular connectors that look very similar. Then there's voltage as you mention. There is also polarity. Most adaptors and devices are centre pin positive but I have a nasty suspicion that Hackers are negative centre pin.

Confused? If I were looking for the right adaptor, even with good technical knowledge, I'd still need to be careful.

There is an alternative. You can get battery holders that will take 6x AA cells. These will easily fit in the space occupied by a PP9 battery. This sort of thing, though this doesn't have the correct snap connectors to directly replace a PP9: https://cpc.farnell.com/multicomp-pro/mp...dp/BT06498

PS: I've had a quick look around and found this which is claimed to be suitable for a Hacker Sovereign. It may well be OK but I can't be 100% sure: https://www.amazon.co.uk/Negative-Centre...B07Y8LSNT9
