Re: FS: Very cool heatsinks

I forgot to mention that they weigh 5.5kgs each. I’ve now annotated the pic to show actual dimensions:

FS: Very cool heatsinks

I have some very large heatsinks for sale - see photo. They measure approx 30 x 30cm and the longest fins are 7cm long. I do not have a dissipation rating for them but you would have to be building a truly monstrous class A amp for these to be inadequate! They also look really cool 8) because of the...

Ray, I was just looking at the LU1014Ds that I got and was reminded of your wanted ad. Are you still wanting some? Cheers Ian

Re: Speaker protection

Not at all. Each component on a power amp board makes the sound . Take I out and the sound will alter or disappear Add a component and it will alter. It’s like a reciepe . I think you are conflating the the functions of the components and any artefacts they may or may not introduce whilst performin...

Re: even more lateral fets

The designers of this LatFET amp have very high aspirations so it will be interesting to see the feedback from the builders. XRK has built a lot of amps so he is well placed to assess it. Expensive BOM though.

Re: Speaker protection

You are right about the 2 camps Ed. There are those that just want to make hi fi gear cheaply and then there are those that see DIY as a means of getting top quality gear at a fraction of the RRP of commercially produced “high end “ kit (with the added bonus of the satisfaction that DIY gives you.)

Re: Speaker protection

They are certainly pricey Ed and I’m not trying to persuade anyone to buy them. Tom charges premium prices for all his boards but he argues that’s because they are premium products. Judging by the feedback of his customers on DIYA and my own experience, I’d say that was fair comment. Value in this c...

Speaker protection

This new speaker protection module looks pretty nifty to me. It protects against DC and eliminates turn 0n/off thumps. It’s not cheap but if you have expensive drivers then you might consider it money well spent. I’ve made one of Tom’s amps and so have direct experience of the quality of his design ...

Re: Bass Speaker for SLOB

For anyone interested in OB bass drivers, SBA are going to be bringing out an 18” woofer specifically for OB. Based on their track record its likely to be a very good performer.

Ali, yes the cable suspension idea seems to have been done by quite a few people and all report positive results from what I can see. Industrial chic 😎
