track to listen to : Time is the revelator

Do not waste time whit the silver plating

I have read the instructions 12 time'S thanks for asking
Tiffo Silver star is a waste of time and money

So I built a Little power supply for one saying WTF ? yes Brunel be proud of it is only a 1000 VA traffo
Attachment 28303
Taking things slow at the moment 8V 150 mA

Attachment 28304

To make my own Nickel acetate

That is a 6 litre batch been running for last 20 minutes

I am going to let it run for a couple of hours and then see if it turns green

For ones thinking WTF gogle up DIY Nickel Plating

Its working pretty well

Nickel Acetate is a pretty green
Plated an old piece of scrap and is really good polish really well the plating is quite thick

I am going to live it for a few days and see

Tiffo Silver was turning yellow after a week or so and polishing would return it to the bare cooper

Nickel Plating sorted

This the part of the power supply inside the mono block's
DSCF2607[1].jpgDSCF2608[1].jpgDSCF2609[1].jpg

The transformers DC filter and a few more capacitors will be on Box 3

I do not need to build that at present as one for my old F5 is working


DSCF2610[1].jpg

You may have noticed the heat sink at the back

The input / Bias board will be mounted on it

I have 2 spare from last build and sink is way oversized but may make my own in future whit a few mods

Last pieces I need for this project ,apart from PSU that I have already

the power boards have been ordered and are on the way
I kept the "Turbo" diodes so that one can make 50W on a 300 mm heat sink or the 100W on the 400mm
I may not fit the diodes on this build as I am not sure what bias will give me 50 C on the sinks, the more bias the more class A, and the diodes limit this as they bypass the resistors at around 330 mA
BTW. I am running 1.2 A on the old ones

I made same progress on re drawing the Input board but is to early to show the new design
Fitted to the sink is a spare board from a different forum

I am not quite so happy about it because of track length and spacing but is good enough for yours

Time will tell


DSCF2616[1].jpgDSCF2617[1].jpg

And this is the part of the power supply that is fitted inside each of the mono blocks
the only thing missing are the by pass capacitors

[Bksabath]

DSCF2618[1].jpgI have same caps that have been sitting in the loft for 10 years or such
DSCF2620[1].jpg
DSCF2621[1].jpg
this is a 10 year old solder joint
don't skimp on this stuff 3.6 % silver is well worth the Dosh



DSCF2624[1].jpg

I am using Rega and Qued speaker cable for the wiring

WTF People ask yourself "Is my wiring looks pretty"

if your answer is no start again and ditch the red blue and what not single cores

and silicon rings around the caps

The Power boards have arrived few touch ups before I order same more

They look Bumpy

That is 10 U (ounces of copper) or to put it on other words 5 times the normal decent quality boards


The spacing for the mossfets is 100 mm

Right thermal load for 50 C at the right bias for a quad on 400 mm sinks or a pair on a 300 mm sink

PS if any one is interested send me a PM
