THEY HAVE BEEN SOLD.
All who had emailed me about them, have been notified.
Now time to order FET's etc while the Aussie dollar is still looking good.
Regards
Wayne

Re: 144 Mhz home brew 600W solid state PA
Yes the above is correct. A couple of days latter I did make contact with the VK2 and was informed that funds have been tight, and sorry will not go ahead with the purchase. So the long and short of it is, I have two pieces of copper that are 182 x 152.4 x 6.35mm. This is ideal for the double 2m PA ...

Re: Grain of wheat 50mA lamps
Lou Yep for DSE, as long as it glows, its a lamp. :roll: Try WES (http://www.wescomponents.com/), the second section (components) in particular page 2-21. They don't have 50mA ones, but have 30 and 60mA units. The smallest being 2.3mm. Let me know if you don't have any luck there with what you need....

Re: 144 Mhz home brew 600W solid state PA
Copper Picked up the last lot tonight on the way home from work. Asked and they said that they have copper in 6mm but it is a different alloy. Not like the nice stuff in the past that was machine grade copper. So maybe interesting to drill and tap etc. The 6mm stuff comes in a bigger size (almost s...

Re: 144 Mhz home brew 600W solid state PA
Copper All I have had more interest in copper. With all orders being met (just), there remains NO MORE COPPER at the suppliers. :cry: I am unsure if the supplier will be restocking this. However never say never. I'm sure if there is a lot of interest and a BIG order is in play, then they may. I am ...

Re: Dick Smith "Lab" Power supply Q1755
G'day all I was interested in one of these supplies. Great for the inside shack. DSE price was $115. But I asked them if it was there best price. The sales rep said that it was on special last month (June) for $99. I asked if he could do it at that price. He said yes. So one was quickly bought. Howe...

Re: 144 Mhz home brew 600W solid state PA
Copper Statistics G'day all I have just picked up the copper from the supplier today. Total weight was 46.5kg. Total linear length was 5370mm. Enough to put your back out. :lol: Plenty of Amps being built, especially in VK3. :D There is a shipment of copper going to Gippstech this weekend. Thanks h...

Copper Heat Spreader
G'day Ron has certainly made high power on 2m (and other bands) obtainable. All of his amps require a copper heat spreader that is at least 6mm thick. Not many suppliers stock 6mm copper plate. However I have located a local supplier for this copper. This copper is labelled as "high cut copper&...

Re: 144 Mhz home brew 600W solid state PA
Copper Update All Just spoke to the Supplier as someone requested a size of 120mm (152.4 x 120 x 6.35mm). Usefull for the HF Amps. The copper cost is calculated on weight + Cutting cost + GST. They also informed me that there is only meters left. The good news, if you go for 10 or more the prices be...

Re: 144 Mhz home brew 600W solid state PA
More Copper??? I have had an enquiry for some more copper plates for Ron's VK4DD amps. Not many suppliers stock 6mm copper plate. The supply said that his was imported from South Africa?? The copper comes in a bar that is 6 inches (152.4mm) wide and 1/4 inches (6.35mm) thick. This was ideal for the...

Re: 144 Mhz home brew 600W solid state PA
Fellow amp builders, Just had an email from Ron, with suggestions when drilling etc the copper. He indicates that it may be difficult to drill. "You might want to bring this under their attention. It is even better if you drill some where non critical to test your drill. Best to use a press dri...

Copper Plates EVERYWHERE. G'day Just picked up the copper plates from the supplier. Well add them all together and they weigh a far bit. Need to go to that gym more often :lol: Well here are a few pics of them. Hope you like them as much as I do. Just the right size +1mm larger all around. (92 x 152...

Re: 144 Mhz home brew 600W solid state PA
Howdy Locating suppliers of copper that have stock in the 6mm region is not easy. However I did locate one awhile ago. They have in stock some EDM (machining grade) copper Extruded Bar, that is 6" (152.4mm) x 1/4" (6.35mm). This is ideal for the amplifiers. I have been extremely busy with ...
