5502 is a solid-state bass amp from around 1984. Not a valve in sight.

I wonder if there is another parts bin full of basses?

Garden centres sell self-adhesive copper tape. You find it under slug repellants. You stick it around plant pots and it stops the slugs climbing up but works equally well in a bass.

[quote name='uptonmark' post='308076' date='Oct 16 2008, 07:04 PM']not for the bass, more for the whole track, i would like to know who played the following tv themes: south bank show and (on tv before some of you were born)...... weekend world title and artist would be appreciated if anyone knows, won`t hold me breath though [/quote] I seem to remember the South Bank Show was Julian Lloyd Webber, Andrew's brother. Try googling "Weekend World". You'll find [url="http://en.wikipedia.org/wiki/Weekend_World"]this[/url]. Last line.

[quote name='simondee' post='308018' date='Oct 16 2008, 05:11 PM']oooh I've got one of these. I really hate the jack lead it comes with - does anyone know where I can get a right-angle one instead?[/quote] You mean like [url="http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=370055180656"]this[/url]

Just supplied some cables. Nice straightforward transaction. A pleasure to deal with.

If you want a 5-string with a narrow slim neck it sounds like you need a Stingray 5. If you want to try a DJ5 why not contact Higgie. I think he lives somewhere in your direction and has my former DJ5 which was a killer.

All it needs now is for one of us to buy it and insist on paying by Paypal.

[quote name='bnt' post='303733' date='Oct 10 2008, 11:47 AM']Re Knobs, you could look at a Stacked knob for volume/blend, too avoid more drilling. You're totally free to drop the tone control altogether, as long as you never need it.[/quote] I think you will have great difficulty finding a stacked log + ganged log/antilog with centre detent for vol/blend.

Now you see it, now you don't.

[quote name='Dave' post='302031' date='Oct 8 2008, 11:38 AM']Cheers for that OBBM, great advice. Valve "black-arts"... I like it! If only I knew what the HT was, I'd be sure to switch it off. I assume it's the "stand-by" switch?[/quote] Sorry. Tech talk. HT is the High Tension supply to the valves. This can vary from 350-volts DC up to 700-volts. This is the lethal voltage that is talked about and is controlled by the Standby switch. However when you switch it off the voltage takes quite a long time to decay so that is why you have to be extra careful. Just switching off does not mean that it is safe to have a poke under the chassis.

There's a lot of nonsense talked about valves. It's very straightforward, simple and as easy as changing a fuse. It's not a black-art. Just use your common sense. Switch off the HT and the main On/Off. Let the valves cool down a bit and then pull the one you want to change straight out. Line up the pins on the replacement and slot it in. Switch the main On/Off back on and allow the valves to warm up, then put the HT back on. Job done. From memory there are no high voltage connections on top of the chassis. They are all underneath. You should be able to do the change easily without removing the chassis from the case. If you do have to remove it for whatever reason and have had it powered or plugged into the mains then do not pick up the chassis by hooking your fingers underneath. Pick it up by the transformers. For what it's worth I've never cleaned a valve because it might take off the manufacturer's labelling and you might end up with an expensive no-name ECC83. If the pins are bent the straighten them carefully with pair of long-nosed pliers.

Works OK for me. My cr@p hearing tells me that the Chi's seem to have bit more depth and low-end compared to the Aeros.

Make a very short XLR-M to XLR-F lead with the screen disconnected, i.e pins 1. This will isolate the phantom volts negative rail from your amp. The DI lead will get its screen from the mixer. Be sure to mark the cable clearly and keep it short so it doesn't get used as a mic lead.

[quote name='Sean' post='299560' date='Oct 4 2008, 07:32 PM']Me.[/quote] Extremely cool. Is it a one-off or from a production run? I can find no mention of it apart from here. Also is it a Skyline?

[quote name='Sean' post='299475' date='Oct 4 2008, 05:19 PM']Interestingly this DJ has no binding and no "Darryl Jones" signature on the headstock. It also has 250 Ohm pots whereas the Aero ones have 500 Ohm pots. What pots do the Fralin ones have?[/quote] My Fralin DJ came with 500K pots. Who owns this one then?

The pick-ups are wired to the centre terminal (slider) so that when the pot is turned right down the output from the pick-up is connected to ground, so there should be no output. If it is not doing this then there will be some unwanted bleed-through.

The wiring looks OK. The white wire from each pick-up should go to the centre tap of their respective volume pots. Could well be a pot problem. You could try checking them with a multimeter. BTW the pots should be audio taper (A) or logarithmic (LOG), not linear.

Post up a picture of the wiring. It sounds like one of the pick-ups is not wired to the correct pot terminals.
