1/ I use ordinary glue to fix output transistors and they fail because of it. In the past seen at both PFM and at AoS and used to try and show how badly NVA amps are made. Latest put on a 2nd hand A40 listing by Emporium Hi-fi at ebay which was libel that I have got him to remove.
I have avoided publishing this before as why should I help people design and build amps, it is far easier to use than the tradition method if more expensive. For me the primary motive is I need to use it to maintain ClassII double insulated appliance regs.
I have also contacted emporium via eBay about those A 40's ...
What happened to these - were they dropped?
Why is the NVA logo on the left it should be on the right.
Thanks in advance.
They went bang but they are glued together so had to be dismantled
I own NVA, the top is meant to be removed, but it looks as if the person who "repaired" these used a sledge hammer. If these were properly repaired by NVA I may have bought them. Can you guarantee they still meet class 2 specs?
New message to: emporiumhificom
Then you should not sell them as they are dangerous.
I await their response.
NVA use cheap plastic cases, can't even use metal, and they are unsafe as they don't have an earth.
Well per usual this explains it all https://en.wikipedia.org/wiki/Appliance_classes
Well I am likely to waste my time attaching a earth wire to a non conductive material like Acrylic, yes I am full of stupidity like that, but some of these knob heads will praise the bit of wire. Acrylic is a plastic the same as gold is a metal, but as with all things there is wide band of uses types and quality. An acrylic case cost more than a metal (steel or aluminium) one - so not done for cost or cheapness - done because it is the most attractive (I personally really like the look), but mostly done because it is the #1 insulator in meeting the double insulated standard.
Now wouldn't you think that somewhere on the forums there would have been someone with this knowledge apart from me, but no, when the likes of Fatpoopy, YWanker and The Bitch were busy abusing me and NVA at PFM about cheap plastic cases and no earth not one person said "hold on what about Class II appliances" why because none of them had a clue what it meant.
More to come.
