DR250 Build, Perth Australia

[SimonD]

I've just found a company in Sydney, TorTech, and bought two transformers to replace the existing one. One is 230 Primary 2X16V secondary at 30va. That will give me about 17V at 240V @ 0.93A (the original is 0.45A). The second is 240V primary and 10V secondary @ 50va (the original is 10va). A little bit of overkill but they will both fit easily. AU$30 each and $15 freight. I'm still well short of the $550 for a PX from a local supplier . I am not sure if both these transformers are stock items as I rang them up and had a chat and he said he had them on the shelf but that they were not on the web page. http://www.tortech.com.au/
I'll do a thread on the conversion as soon as I get the transformers. Cheers S

Hi Folks, I got the first coat of DuraTek on box 1 last night but unfortunately it had an alergic reaction to the white primer that I had used on the top and bottom panel so that some white patches were showing through . I decided on the "task of least persistance" approach and let it dry for a few hours then put another coat over it. Thankefully when I checked it this morning it was perfect, no sign of any surface bleed

I wont make the same mistake with the T39s

Progress wise, I am ready for final assembly as soon as the DuraTek is done. I ordered some black Penn handles to replace the chrome ones that I bought previously. I couldn't go to so much effort with surface finishes etc. and ruin the asthetics with shiny silver handles could I?. I am also looking for some black wood screws for the Penn corners if anyone knows a supplier in Oz?

I plan to put some electrickery into them by the weekend

I saw one trick which was to push the screws into some cardboard, hit them with a spray bomb, and let it cure. Bingo, black-headed screws.

Even if you find black screws you want to do that. The oxide coating used on black screws doesn't prevent rust, paint does.

Thanks for the info guys, I was lucky enough to pick up some Florentine Bronze plated screws from the local Mitre10 hardware store.



I am still waiting for the new black handles to arrive but all the rest is complete. I'll load them this evening and give them a test.











I have to say I am very happpy with the overall finish etc.

Now on to the T39s

That's an awesome red there!

[Scott Brochu]

Good build
I like the contrast in color.

[SimonD]

Thanks guys, just a couple of shots of the final assembly.







In the studio at last, I think you can see where the red theme is coming from







I also got to mount the old mackie permanently in the room.

Be careful....when you stand 'em up like that all the sound will run out the bottom.

Ahhhhhh, thats what the problem was at last weeks rehearsal, I though we sounded a little flat

Hi Folks, As I will be running these up for the first time tonight I have been looking for some setup info but am overwhelmed. Can someone please answer these simple questions:

1) Where should I be measuring the voltage from? amp output, crossover terminal, speaker terminal......?
2) What is the maximum voltage that I should be putting into the DR250s with the Kappalite 3010MB(8 ohm) and 2 x ASD1001S (8 ohm)
3) What is a suitable frequency for the test signal?

Cheers S

[Tom Smit]

1) from the amp output
2) when it's excrutiating loud! That will likely happen before you can hear the speaker distort
