Default Toroid Trans and empty chassis

This chassis and transformer are suitable for an amp such as a Hafler DH-220. The toroid transformer will drive a 115 watts per channel stereo amp with supply rail voltages of 65 VDC.

The diode bridge and cap mounting rings are included.

The chassis dimensions are 5.25" tall, 12" wide and 10" front to back. The face plate is the standard 19" wide for rack mounting and includes an ON/OFF switch.

You can see cut outs on each side. It used to have Hafler style heatsinks but you could easily mount your own. The chassis has a nice fitted lid with ventilation holes. The back side has terminal strips for inputs and outputs. The back panel also has 3 fuse blocks for AC in and speaker outs. A level control for each channel is also mounted on the rear panel.

Price is $35 plus shipping for 20 pounds to continental USA only. I will box carefully and ship via FEDEX.

PayPal is preferred.

Here is a different view of the chassis -- with the top removed.

You can see the mounting rings for the PS caps. Note the nice PCB which attaches to the tops of the PS caps and has fuse blocks for the 65VDC to each channel.

You can see the cutouts on each side where driver boards can attach to your choice of heatsinks.

Default Toroidal trans and empyt chassis

Here is a rear view of the chassis that shows fuses for speaker protection, level controls, and screw terminals for signal input and speaker output.

The electrolytic caps on top of the chassis just happened to be there when the picture was taken. They are each 6600 uF 60 WVDC and are free if you want them.

Default BUMP!! Lower Price

How about $25 plus $15 flat rate shipping cost -- via FEDEX.

The case includes diode bridge and transformer all wired. Just add PS caps and hook up your circuit cards. Case can accept several different sizes of heatsinks.

brutepuppy,

You have email with PayPal ID, etc.

I'll ship upon receipt of confirmed payment.

Do you want those 60 VDC caps? Or, how about a pair of Sangamos 75WVDC 10K uF 2" X 4"? No charge for the caps.

Thanks,

Dick

Default Clarification of transformer voltage

For clarification the transformer is center tapped 45 - 0 - 45 VAC. Therefore, after rectification it can supply the 65VDC as listed above.

I estimate the transformer to be rated at 450 VA.

Thanks for looking.

Dick
