Need Help Sourcing Parts

HipoFutura · 6th December 2006, 06:57 PM

I'm having no luck finding a couple of parts needed to complete my AV400.

I'm looking for a transformer with 115V pri & 9V/1amp secondary. As well I need a 25 Ohm 15 - 50 watt metal clad resistor.

Any help with a source and part number is very much appreciated.

or RHC-25-ND There are a bunch. Just search for resistor, then select wirewound, and select your criteria from the lists.

Look around the Hammond site and you'll find a transformer for sure. Here's a page where they have a 10v/1.2A secondary.

dsavitsk, I saw that toroid, but hated to spend $15. This transformer is just to supply a power-on slow start circuit. I was hoping to find an inexpensive tranny. The "TDH35P25R0JE-ND" resistor is great. Thank you! Don

I just placed the order with Digikey. The tranny was a bit much, but I want to get this project wrapped up so I can enjoy the amp. The amp is pretty well done. I've built the case, assembled the components, etc. Just need to build this slow-start board. Thanks again guys! Don

Look on ebay for either 0-9v 10VA or a 18VCT 10VA . I used a 18vct 9 vac for softstart and 9vac for cooling fans and power on indicator works great. payed 8-9 dollars on ebay including shipping.

Hippo how hig are your main rails in that amp?

HipoFutura · 6th December 2006, 10:54 PM

The rails are 70VDC.
