The former will require significant redesign however. Want to gain comprehensive data for LMK to optimize the supply chain include cross references, lifecycle, parametric, counterfeit risk, obsolescence management forecastsplease contact to our Tech-supports team.

I’ll try this one and see how long it lasts. It’s datawheet Soundcraft CPS power supply, this is the heat-sink, devices are insulated. Adding a much bigger heat sink mounted to the chassis top plate really helped. I can add some smaller heat-sinks inside the cabinet, using one of the TO-3 screws unused with the TO device. Is my math right? Other possibilities include adding a series pass transistor or datasheet drops so that lm78812k LMT doesn’t take the brunt of the drop.

That’s what I did it worked fine. I’ll check the mixer specs to see if I need a second device in parallel, but I think with 25W it will be fine. I don’t have the plastic covers.

You may be better off drilling new holes for the TOs, using the existing TO-3 holes may not work well. Pict from the internet, not mine: The soft silicone insulation at least removes some of the air voids, but still not better than metal-metal contact.


Why this Voltage regulator is so expensive ??

Maximize air space around it as well. NTE is the replacement and cost less. Mouser link No Affiliation https: If it blows this next month I’ll modify the circuit to install To devicesperhaps with a resistor in parallel. WatthourJun 24, Check the 78xx regulator application notes for how to use a high power parallel bypass transistor to make a high current regulator. Careful, bare metal contact is always better than adding anything in between – especially air voids.

Torque down properly – don’t overtorque and cause the flange to bend or too little, leaving air voids. No, create an account now.

It’s been fatasheet year so far and not one time has it shut down from over heating. Do you already have an account? Bill Ferris and Lavane like this. The Valley of Chief Black Hawk. The PS is rated 1. I redid a Soundcraft Delta power supply that had like 5 of those TO-3 guys in it.

Register Log in Shopping cart 0 You have no items in your shopping cart. Is the metal TO-3 case too expensive to manufacture? I’d suggest sinking it directly to the chassis with an insulator and lots of thermal paste. You must log in or sign up to reply here. Wing Shing Computer Components. Quickly Enter the access of compare list to find replaceable electronic parts. I’m pushing it hard and although a TO pkg. The new type of capacitor has a space-saving design with two, three or even ten identical capacitors connected in parallel on the same terminal to increase the capacitance.


They’re long gone out of production. That explains the price.

I know its real because its from Yes, my password is: You could mount the regulator somewhere else to make it easier to add one if needed as sKiZo suggested.

If your close to the max extra heat sinking should work.

I’d also be getting the TO and heat sink it as necessary. Discussion in ‘ DIY ‘ started by elnaldoJun 24, Is it some very special part? Log in or Sign up. Funny, I have a new old stock that I purchased in for a power supply project and ended up using a to instead. I don’t think the mixing console it feeds will draw 1. I think I’m going the TO route I can get it locally. Is the TO-3 version much better than the plastic TO?

It’s likely that not many are made in T cases. You may still need to check whether the circuit will support the extra current from the ADJ pin.

I’m running a dual regulator right at its max rating to regulate a pair of B tube filaments.
