  1. If your circuit is the one above with the switched resistor in the op amp feedback then the sound you are hearing is because of a small dc offset in a very sensitive part of the circuit. You could quickly try switching in a resistor in the other part of the feedback ie the grounded part. Try maybe 2k plus 2k switched. Better yet swap round the resistors and low cut capacitor so resistors are connected directly to ground. Hope that makes sense and is worth a try before the passive attenuators option. Good luck
  2. Nice old Dual cs505-3 turntable for sale. In full working order. The only points to note are the cracked cover, which has been glued back together and that the cartridge shown in the photos is not included in the sale, but is fitted for test and demo purposes only. Can be seen and heard working in Wells Somerset.
  3. Hi Stew, The soldering on the jack socket does not look like a factory job to me, so it is possible that the socket has been re-soldered or replaced at some point. They're not the most reliable of components and I've lost count of the number of sockets I've replaced on instruments, including Warwick basses (even made in Germany instruments) that use this type of jack. It is possible that it's been incorrectly wired. The ring connection should be connected directly to the battery negative and nothing else. The tip is signal and sleeve ground. As the bass works when a fresh battery is fitted, it is likely that the tip is correctly wired but the ring and sleeve may be reversed. If you have a TRS jack lead and a multimeter, plug the lead in and check for continuity between the ring and battery negative terminal with the battery removed.
  4. 1990s Crate GX80 guitar combo for sale. In good condition this is a 2 channel 80 w solid state amp with reverb, made in the USA with single crate badged 12" speaker in open backed cab. It all works as it should and is reasonably light and compact as well as being quite loud!
  5. I estimate the packed size would be 70cm x 30 x 18 and weigh 5Kg. That's allowing for a good layer of bubble wrap and cardboard packaging. Based on this, UPS are quoting £37 (classed as a medium size package) Their price is based on size and not weight, so more packaging could possibly be added without increasing the cost significantly. There is likely to be customs import duty and taxes payable as well and I've no idea how much that would be. It may be a better option for you to arrange collection from me, if it's still of interest.
  6. Peavey envoy 110 guitar combo. Solid made in USA construction in good condition. Single 10" speaker in open backed cab. 2 channels plus reverb.
  7. Marshall's own modelling amp, featuring digital versions of all their classic valve guitar amps from the 60's onwards. There are 100 factory presets as well as the ability to download others from the Marshall online forum, or create your own either on the amp or using USB connectivity and a web browser or app. There are 24 built in effects of which up to 5 can be used simultaneously. This is a great amp for those that like the Marshall valve sound but can't afford to buy and maintain a collection of vintage valve amps! It uses a single custom 12" speaker in a fully enclosed cab. This amp is in very good conditions and with it's 50W digital power amp weighs in at 13Kg.
  8. Sorry. I've only just seen your post. I'll look into it and get back to you.
  9. Various 12" speakers for sale, surplus to requirements. Mostly dual cone full range, one McKenzie bass speaker. Looking for about £30 each but open to offers?
