Here is a good read on soft start circuit.

Joe has a soft start circuit that answers the concerns brought up by Rod....

Perry, the one you linked to is 240v?

Yeah, they got them in 110 too.
Its just a solder jumper.

Got the monster toroids for the Monster Mono's.... Damn, almost hurt myself lifting the boxes. The Beer is only there for size comparison, I don't touch the stuff.

Yowzers!

 

[WOPL Sniffer]

Of course, no paperwork so I had to email the factory to see if they had a drawing.

MADE IN HONG KONG.... Not no Cina stuff

 

[orange]

The UK gave Hong Kong back to Cina for a late Christmas present at the end of 1997...

 

[WOPL Sniffer]

NO SHIT... WOW, yer really on the ball Steven

In case you didn't figure it out, that was a joke...

... and the end of the British Empire

Perry what part number are the units you bought. Where did you get them from
let us know

thanks in advance

I got these from a guy online who buys shit from businesses going out of business. Apparently these were custom wound for ADAIR Audio which was out of Lynwood Wa. They built, among other things, a 1200 Watt Sub amp and I believe these toroidals were used in that amp. They have since closed up shop (2007???).

I bought the last of them from the guy at Apex Jr

His name was Steve Slater, nice guy.

I'm now trying to get the HongKongians to give me the specs and drawing for them.

I hate it when they bite your neck....

 

[Northwinds]

Man, I am excited. This is the beginning of the Phoenix Amp Wars. Between Lee's and your mono bloc builds, I expect to see some major ridiculousness

Amps as big as SX-1980s and you need two of them!!!!

Life is GOOD

 

[WOPL Sniffer]

2 of them??? Plus the power supplies..... Look at my avatar bro.....

Perry, Black and white, Brown and blue are the 2 120 primary windings, I ran mine in parallel by pairing Black/blue and Brown/white

Secondaries were Red--Yellow --Red ------------169 center tapped
Purple---Grey---Purple----------24 volt center tapped
Orange---Orange-------- something weird like 18.....

 

[WOPL Sniffer]

cool, these got 24V??? I can run a vibrator recharging station out the back.

 

[laatsch55]

Near as I can tell Perry they are 800VA...

 

[WOPL Sniffer]

is that why you doubled them up? I think you said you were running 2 of them in parallel. Did you really need to go double?

 

[laatsch55]

Hell Yeah!! Probably 20 of em...I think the 24 volt winding is 25 amp....

 

[WOPL Sniffer]

OUTSTANDING

The transformers themselves or the 120 windings?

Yeah I ran two trannies per side. The idea was to drive high power into 4 ohms all day, AND to put a lot of wattage into a 1957 vintage pair of 16 ohm Klipsch Kornerhorns. Stephen is driving those with a pair of Bryston 7BST's, 900 watts per....can't match that....but at around 600 per with the WOPL sound should tickle the vintage K's just fine.
