Are you implying that RA products may be a little overpriced ??

PS It looks very neat - are you going to reveal the diagram etc. ?

Well the "superclamp" is just two parts, lol.

I'd not like to be a voltage spike in Rowey's house! 😱

Big caps across the mains clearly work. I'm going to rehash and upgrade my mains filter box soon. Will post results on here.

I fully support all RA products as they all work, but my own company do the equiv noise plug to the silencer and its 1/2 the price. Also our surge plug is 1/2 price of his LOL.

We make very little on these due to the electronic components , plug case , stickers and labour. So I can see why he charges what he does.

I have a mains monitor and believe me when I say there are spikes. Some of them are over 600V.

Buy yourself a 600V GAS arrestor and wire it across L-N (make sure you have a breaker) and leave it on. If the breaker trips you have had a spike of 600V+.

There are even more spikes around the 350V mark. These spikes saturate transformers stopping them working correctly and thus effecting the secondary supply into your equipment.

Hi Rowe,
You don't need to convince me, I believe you.

Just appealing for details of your solution.

You said "own company".
Do you use trading post?

I dont have a trading post. Not thought to lol

We have an audio section that will have an overhaul when we get out regs made.

The audio is about 1% of our business (more of an hobby really) and am hoping for it to grow. Its all about getting peoples trust and good feedback and cutting into the bigger companies business.

Hi there,
So in diag mods the step 0 shows nothing, everythings power up ok.
Then press next and step 1 is on : laser goes up & down non stop and laser is on. Step 2 the disc spins OK...
But when hit play error 02. Any clue of what can I do?
Brent how much will you charge me for fixing it? I'll loose my CD53 if not...
 
Here I am the stupid guy of the thread... yes I think this time the word is the right one:
I've got one less screw when I colsed it back last time... the bad idea was to screw a screw... not in a fixing hole but in the adjustable resistor for focus... ya ya you can laugh at me I deserve it...
A question, if I need to put back my dc blocking caps, BG will help not loosing too much bass here like OEM ones? (stop laughing and answer!!!)
 
Evening all,

Probably a bit pointless to show but here's the single ground connection between CDP and PSU. A salvaged speaker binding post and a thick lead I got via Ebay, with silver plated bananas.

10mm^2 wire from star earth to post, excessive maybe :devilr:

I had to isolate the post from the chassis with plastic salvaged from packaging, so as to not mess up my carefully considered grounding scheme!

Two nights ago I had a nightmare session looking for the shorts between audio ground and safety earth in my preamp. One more problem sorted at least!

This Dire Straits, Live at the BBC 1978 sounds nice!

night 🙂
