Yes, you can hear the internal speaker, so I'm guessing the amp is working but the screen just stays grey. I loaded Jet Set Willy on the working Spectrum and it makes the same sounds as the Spectrum that isn't working when its loading apart from after about seven seconds the tone changes and then go...

Guys, I bought an amp to try and take the workload out of putting one together but it didn't work. The amp works fine with my other Speccy but I had the usual problem on the problematic console. Attached is a spec for the amp. In your opinions, should it be powerful enough to do the job? If not then...

Cheers, guys. @1024MAK Looks like I need to gather together a few bits and pieces but hopefully this'll sort the problem! @Moggy My soldering skills aren't fantastic but they're adequate, so if I don't get any luck with the amp x20, I'll get the soldering iron out. I'll probably be a few days sourci...

@1024MAK I was just re-reading the post you previously directed me to about boosting the audio https://www.sinclairzxworld.com/viewtopic.php?f=7&t=3541&start=10#p36670 and noticed the part about old PC speakers being something to try. Guess what I threw out two sets of last week?! :x I'm off out in ...

No worries, Mark.

Good luck with court, I hope it went well.

Cheers,

Kieran.

Hi Mark, thanks for getting back to me. I appreciate it after it took me so long to get back to my original post! :oops: Having read your reply, I'm wondering whether I've bought the right amplifier or should I have bought something more like this: https://www.ebay.co.uk/itm/262610277188 Cheers, Kie...

Hey guys, I originally created a post some time ago ( https://www.sinclairzxworld.com/viewtopic.php?f=21&t=3292&p=42854#p42854 ) about the sound problems I was having with a ZX Spectrum but I've only just now come back to the project, so I've created a new post here because I don't know if a post fr...

Hi guys, it's been a while since I've had a chance to look at the Speccy for one reason or another but I've finally got a bit of time to work on it again and hopefully, get it working one way or another! I bought the LM386 Module 20 Times Gain Audio Amplifier Module F Raspberry Pi Arduino from eBay ...

Thanks, guys. Lardo, thanks for your help and typically, they've now sold out! :roll: Mark: on the subject of the audio power amp, is there anything that you know of that works well with boosting the audio? A particular type of amp? I haven't got one so I'll need to buy one. Thanks again, guys. :)

Can anyone help?
