I believe (simply from reading on here) that, when they go wrong, they are not easy to repair, i.e. the usual fix is to swap out the main board, which can be expensive. No doubt someone with hands-on experience will confirm or deny this in due course.

Why does this company think that musicians who have been happy with one basic sound for 50 years (OK, two at a stretch) are now suddenly going to want 15 million sounds? Even guitarists have been happy with a Strat and a Les Paul, maybe a Tele at a push, for decades. This is a product looking for a market that isn't there. The Gamechanger thing is just embarrassing. IMO, of course.

Adrian bought a Jazz Bass pickup from me. It was a very easy and straightforward sale and Adrian was a pleasure to do business with.

Bought a pair of speakers from Richard, who very kindly sent them off first-class post. Very easy chap to deal with and comes through with what he promises. Thanks.

Bought a pickup from Rich, which was well packed, despatched promptly and exactly as described. Buy with confidence!

Bought a keyboard from me. No hassles. Easy transaction. Recommended.

Just noticed that Luke has a feedback thread. Sold him a Precision a couple of years ago for a not inconsiderable amount of money. Payment was prompt and Luke was a pleasure to deal with. Better late than never :-) Stevie

I swapped the fan in my Trace AH-300 because it was noisy. It was relatively easy to do. The fan connecting wires were held in by two small screw clamps attached to a circuit board. The only awkward part was having to move the power amp board because it was stopping me from getting my screwdriver into the the clamps when I came to replace the wires. When buying a new fan, choose one that has a similar consumption to the one you are replacing. In other words, if the original one is 0.1W, that's what you should be looking for. The best place to buy them is a specialist computer store. I recently bought a Panaflo for about £3.50 from Scan computers. The good ones aren't very expensive - so go for a respected brand. It really is pointless soldiering on with a duff fan when they are so cheap and easy to swap. There are plenty of tales on the web of duff Trace Elliot fans causing the output transistors to blow up. Depending on the output trannies, the repair can be well over £100.

Not only that, but 3.9 ohms is a preferred value and therefore much easier to obtain than 4 ohms.

[quote name='Phil Starr' post='1044858' date='Dec 2 2010, 11:37 AM']I'm sorry to disagree with you but this is a bit silly.[/quote] It's not only silly - it's complete bollocks. The output from the vent is delayed in time compared with the output from the front of the speaker cone. Thus, a reflex speaker cannot by definition have a transient response as good as that of a sealed speaker - because that delay is always present when there is output from the port. [url="http://en.wikipedia.org/wiki/Bass_reflex"]http://en.wikipedia.org/wiki/Bass_reflex[/url] Let us listen to what a real speaker designer has to say about this, shall we? Cue Mr. Siegfried Linkwitz. The name may be familiar to you if you have an interest in loudspeaker design. ([i]On his decision to use a sealed cabinet for his state-of-the-art subwoofer[/i]) - "I did not consider alternate approaches to subwoofer design as [i][b]acceptable for meeting my goal of accurate sub-bass reproduction[/b][/i]. This includes [b][i]vented[/i][/b], passive radiator and acoustic bandpass woofers. They all rely on [b][i]resonant energy storage[/i][/b] to increase efficiency and to reduce size. ([i]On his choice of a sealed alignment for his Pluto speaker[/i]) - "Finally, most box speakers use [b][i]vented [/i][/b]enclosures which means [i][b]stored energy[/b][/i] to increase otherwise insufficient or distorted bass output. PLUTO+ is sealed with a Q = 0.5 roll-off at the low end of its frequency range for [b][i]optimum highpass transient response[/i][/b]." I'd be very interested to see anyone attempt to prove Linkwitz wrong on this. Over to you Mr Fitzmaurice - or are you too busy designing loudspeakers

[quote name='bumnote' post='1046226' date='Dec 3 2010, 12:29 PM']To add to the debate, I have a mini 1x15 and it doesnt sound particularly nice to me, I can only describe it as Boxy whatever that means, while I love the 4x8 for its compact size and its sound[/quote] I have two of them in the garage, which I am very slowly converting into 12" cabs. I posted some measurements of the cab on here a while ago showing a (not very nice) bump at 100Hz. You could try pulling that frequency down a touch with your eq. I'd equate 'boxy' with a problem at a higher frequency than that. There is a very good chance that lagging your cab with wadding will reduce the boxiness, because boxiness is the typical sound of a box that's not lined IMO.

[quote name='ezbass' post='1046421' date='Dec 3 2010, 03:00 PM']I phoned Ashdown and bought the new neo versions that they fit in the Superfly cabs.[/quote] From what's been posted on here, Ashdown replacement speakers are quite good value. As we know, some bass companies charge the earth for spares. I would definitely consider that an option. The internal size of the Mini 15 cab is 55 litres. At a rough guess, that would make the internal size of the combo, what - 40 litres? That's quite large for a 10", and larger than the Celestion neos like to see. If you want a Celestion, you'd be better off with a 12". The Eminence Deltalite 2510 works better in a large box. The downside of that driver is that is shrieks like a banshee at 2kHz. Some people equate that with clarity, but there you go (and you can always pull it down with the graphic). If, as you say, the purpose of this exercise is to cut down on the weight of the combo, it might not be as successful as you think (as Bumnote has pointed out). A Deltalite neo weighs 2.1kg. The ceramic magnet Celestion BL10-200X weighs 3kg, and I would suspect has a larger magnet than the Ashdown driver you have at the moment. Before you spend any of your hard-earned cash, I'd suggest you weigh the Ashdown driver.
