Teebs Posted February 5, 2020 Share Posted February 5, 2020 (edited) I have an Ibanez Promethean P20 bass practice amp which I use for quiet practice at home in the living room. My wife got the carpets professionally cleaned yesterday - I didn't know that she was planning to do this, or I'd have moved the amp. The amp was covered & unplugged, and there is no obvious sign of damp, but the amp is no-longer working. There is power to the amp - the LED lights and faint noise can be heard through the speaker which increases as the volume is turned up, but no sound when either a bass is plugged in to the input (I've tried 3 different leads and 2 different basses), or MP3 player plugged into the Aux In (I've tried 2 different players and 2 different leads). At present, the amp is sitting in a warm, dry room - I'm hoping for a miracle! Is there anything else that I should be checking? Or doing? Thanks in advance Edited February 7, 2020 by Teebs 2 Quote Link to comment Share on other sites More sharing options...
Muppet Posted February 5, 2020 Share Posted February 5, 2020 Any sound out of the headphones socket? Quote Link to comment Share on other sites More sharing options...

No - only a faint 'hiss' - the same noise the amp makes when it's working. I'm hoping that the damp atmosphere in the front room has got into something, but will evaporate off now the amp has been moved to a warm, dry room.

Skinnyman Posted February 5, 2020 Share Posted February 5, 2020 Can you get the back off and give it a blow with a hair dryer on a medium setting? Quote Link to comment Share on other sites More sharing options...
Teebs Posted February 5, 2020 Author Share Posted February 5, 2020 I've had the back off to check fuses / obvious signs of magic smoke release, so I might give that a try SM. Ta Quote Link to comment Share on other sites More sharing options...

Ta You're looking to dry things off not cook them so take it steady 😁 You could also try filling a paper bag with a dessicant (rice would be my choice), put it in the back of the amp and put it in the airing cupboard overnight. I'd be careful not to spill the rice though as it gets everywhere..... 1 Quote Link to comment Share on other sites More sharing options...
Teebs Posted February 5, 2020 Author Share Posted February 5, 2020 Hmm... We have some progress. The aux in socket now works & sound through the speaker. It wasn't doing that earlier. Headphone socket also works now. Main input still doesn't work - I think I'll leave it a bit longer, and if it still doesn't work, I'll remove the preamp board from the chassis & check the solder joints. Thank you for your suggestions BC people Quote Link to comment Share on other sites More sharing options...
Hellzero Posted February 6, 2020 Share Posted February 6, 2020 Are there send and return jacks on this combo ? When yes, shunt them. 1 Quote Link to comment Share on other sites More sharing options...

Hellzero Posted February 6, 2020 Share Posted February 6, 2020 Let it warm up, as it has partly succeeded for now. Static electricity is also a real evil, just as humidity. 1 Quote Link to comment Share on other sites More sharing options...

Teebs Posted February 7, 2020 Author Share Posted February 7, 2020 Well, I've resoldered the input connections, but the problem persists Can anyone recommend an amp tech near Manchester please? Thank you 1 Quote Link to comment Share on other sites More sharing options...

He sued my mum's bungalow (and contents) off me for 'looking at him in a funny way'. 😬 7 Quote Link to comment Share on other sites More sharing options...
Teebs Posted February 10, 2020 Author Share Posted February 10, 2020 It's not an expensive bit of kit - about £100, so not worth chucking accusations around. I just want it to work - I loves it I does! 1 1 Quote Link to comment Share on other sites More sharing options...

Raymondo Posted February 10, 2020 Share Posted February 10, 2020 Have you thought of setting up a "go fund me " page ? They are very trendy I believe ;you might be able to afford a decent practice amp then. I'd send in a couple of bottle tops and a pack of 51 playing cards to help raise funds......I lost the 7 of clubs down the back of the sofa 5 Quote Link to comment Share on other sites More sharing options...

BassBunny Posted February 10, 2020 Share Posted February 10, 2020 Gee Electronics in Warrington would be your best bet. Problem is just to test and establish where the problem is will cost £25 - 35. As it most likely will then need a new PCB, the cost, (if you can get one), will likely easily outweigh the value. Roland Lumby is another possibility. Have you checked the Amp Techs thread. 1 Quote Link to comment Share on other sites More sharing options...
