Oh, for goodness sake, stop being so pedantic and take note of what was written. I made no personal comment. I referred to no one in particular. I commented on solicitors clerks and shepherds. Surely it is fair to allow the reader to conclude for themselves about what I wrote. You really are taking moderation to an extreme, not far short of what happens on AOS, albeit without the bias. Very disappointed. It was perfectly transparent who you were referring to, and what you think of them. That much is also clear from what you've just written above. It was not addressing the topic and we've repeatedly requested that contributors do so.

I'm not sure what the motivation is for building an LDR pre considering you cannot sell it on and will have to undertake specialist disposal. It appears since people were informed of the illegality there is a bloody minded attempt to go ahead anyway. If this is just to get at Richard Dunn for pointing out the facts and being right I am quite perplexed as to why anyone would be stupid enough to waste their time and money. Sometimes I think there are certain enthusiasts on these forums that have serious psychological issues. Please wake up and get real. Your post is completely wrong. Certainly the ownership and use of an LDR pre-amp is not illegal. You can legally sell on a DIY LDR pre-amp. If disposal is an issue, certainly consulting your local authority would be appropriate and result in easy appropriate disposal. RD has pointed out facts according to his own understanding but factually he is totally wrong, per SE. Why do sheep keep repeating his nonsence before stopping and working it out for themselves?......are yes, it's because they are sheep!

As I understand it having spoken to Farnell, LDRs are permissible as there is no alternative. However in the case of pre amps, as LDRs compand, they are an awful choice for a hifi pre amp and should, in my opinion be avoided in this role at sll costss. In the case of a Joe Meek style, classic "suck and blow compressor" they are irreplaceable and I have 2 I would not part with. The amount of cadmium is miniscule and not worth worrying about, when compared to the mountains of cadmium in old batteries and paint

Here we have the two extremes: being accused of pedantry when it has been necessary to moderate some comments in order to stop the mud slinging, and then having individuals being told what they can and cannot construct in their projects through transparent attempts at bullying anyone who wants to use an LDR (who obviously has psychological issues)! WE are not trying to 'get at' anyone, and at least we gave you a place to vent.
To be accused of doing what happens at AoS and simultaneously hosting thoughts from the remote presence at HFS is quite funny if it wasn't a little sad.

Thanks Paul, for the first constructive remarks on the subject for some time.

I have to say that I'm rather less concerned about the threat of my death or imminent demise from James' pre-amp than I am about the effect on the general population from the possible release of things such as benzene, toluene, cadmium and arsenic into groundwater from rock that is fractured in pursuit of fossil fuels.

The amount of cadmium is a red herring. It is the principle of picking and choosing which laws and the morality of the issue. If you don't think that is relevant fair enough.
Pauls comments are confusing as they seem too question the legality issue. As far as I can see rhos regulations prohibit commercial activity.
P's. For what it is worth I don't agree worth the moderation but I do think those that have done it have implemented it have done so without bias even allowing for the fact it would seem nearly everyone who disagrees with me is unable too post without ad homien.

Legal or not, LDRs should be advocated as a tone control, not the best thing since the proverbial. To try to pretend that an LDR preamp is transparent is self-delusion of the highest order. There are active preamps using transistors and valves that do far less damage to the signal than a light dependent resistor. Might as well build a "control unit" with bass, treble, scratch and rumble filters. At least one of these is honest in its intention.

Not having looked at them in any depth, I've no idea whether they are operated in a small part of a reasonably linear section of their operating curve within the preamp design.
However, that's for the component thread rather than here.

Too many juniors tring trying to moderate - leave it to the adults children...

Commercial LDRs Are not available so are you suggesting he is concerned the diy community will forsake nva passives and build thier own LDR's preamp. If so those diyers making passive pre amps must bring him to tears. Rd as more than enough buisness and the last thing he would do is discourage diy to make a sale. As I have 4 kids and a wife on permenant maternity leave hifi finds are in short supply. when i bought some power amps he sent me a volume pot and info to make my own passive. He also sold me some nva cube drivers at cost and doped them free of charge. If it's fine to take issue wirh opinions but if you are going to question motivations you need to know what you are talking about.

I've had to edit your quote, DQ, to match my original moderation. We won't question RD's motives here as he has no right of reply.

The following information has been kindly sent to the mod team and contains very useful references and facts. I make no comment on it as it speaks for itself.

Exactly what RD said . As an aside , their efficacy is not the issue , for the purpose of this thread I have assumed they make wonderful pre amps . I dont think there is anyway any debate as to their SQ will ever be resolved It would seem however the legality issue as been resolved and I will repeat the one germane question , in a country in which the use of dangerous substances is slowly be surely being eradicated and it must be a matter of common ground that this is a good thing , is it okay for a DIY to rely upon a law in flux and build a DIY version of a product that is not legal commercially ? This is a question for the individual , but it seems as far as this issue is concerned , unless something changes ,there is nothing else to sayt .

Facts are good, as I said earlier. I also linked directly to the actual legislation, but it seems none of the contributors to this thread could be bothered to actually read it, much less quote from it, so it is good that we have an easy to digest precis here (.....at last).
