Subject: Re: [Simmons Drums] SDSV Cymbal Card Repair?

From: Malte Rogacki <gacki@...>

Looks like a voltage regulator to me.

The cards only get +/-15V (according to the schematic) but some of the
digital stuff needs +5V.

Could be merely an 7805.

The schematic doesn't show it though; but it shows the need for +5V.
