A few more windings on on the transformer datashete have helped headroom part of the design flaw upstream of the regulator. Sorry, no images have been uploaded yet. If you Buy It Now, you’ll only be purchasing this item.

Could be an add on to the PinWiki reset list??? All you have to do now is run AC to the switching power supply and adjust the voltage. I then reinstalled the original power board and the reset was back. Hi all I have a reset problem with my BSD.

On the other hand, the output “1” level of 74LS latch does not go to Vqc without an external pull-up resistor. Some reading materials on reset issues: Did you know Pinside is able to run thanks to donations from our visitors? The 12v digital has a trivially light load whereas the 5 volt supply is pretty much maxed out even with brand new components. See the seller’s listing for full details. I did notice that the regulator you use in your board was made by the same company that makes the k replacement part also makes the regulator that you are using.

Too bad Pinwiki hasn’t kept pace with these contemporary best practices – it still lists the cut-a-trace and install a resistor method to up your voltage You are covered by the eBay Money Back Guarantee if you receive an item that is not as described in the listing. Peter chow anyone lol? You can plug it right into the service outlet if you want to keep it super simple, the CPU would still run if you switch the pinball off though.

I was going to reply with something similar, but you’ve stated it perfectly except for the typo calling the LMK an LM This page was optimised for printing. I think the point that Rkahr makes is still valid. Delivery times may vary, especially during peak periods. Solider a wire from the power supply ground to the LM ground. BR2 would be the last thing I’d change.

I have been an amusement route tech for a very long time.

Get the item you ordered or get your money back. All specs in that datasheet are irrelevant though as neither one was used in the power driver board. I pushed it again and yet another reset. Just to make sure, I dipped the board in holy water and threw in a couple of garlics under the play field.
