Best laid plans...
I think I shall call this one Sinclair’s revenge.
Not my doing! I desoldered the resistor and it fell out. Clearly this one had the aerial lead unplugged quite a few times!
Sadly my soldering iron is not up to the job of removing the modulator to fit another.

Fit a new panel mounted phono socket in place of the old one. The downside is that you almost certainly will have to modify the plastic case

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.

Re: Spectrum+ 128K Toastrack composite out
After a bit of pursuasion with two soldering irons I managed to swap modulators. And have a nice composite picture, thanks Mark!
However the colour ghosting a little off putting.
In the spirit of this franken speccy I notice there is a mod that can be done to reduce this -

Is this a reasonable mod?

Re: Spectrum+ 128K Toastrack composite out
I’ve never tried that mod. But the article appears reasonable. So go ahead and try it.

Re: Spectrum+ 128K Toastrack composite out
Well, gave it a go and it has improved the main menu significantly but Manic Miner still looks like a 3 year old added the colour to the screen with a medium sized paint brush! Although that is an improvement on how it was (2 year old with large paint brush) it is still pretty poor.
