Early RANE SM26 schematic

Hi All... I am new to the group and hope someone may be able to help. I have an early RANE SM26 on my bench and in need of a schematic. This unit does not use 7815 type voltage regulators but does have the power supply integral to the unit. Since RANE was bought out (by In Music Brands I think) information has been a bit more difficult to obtain. There is a later SM26 posted on their website but it is newer than the one I have, If anyone has a schematic I would greatly appreciate a copy.... Thanks

Fixing UA La-610 Compressor (need schematics with voltage points)

Hi guys,

Like the title says, I got one of my two LA-610 who doesn't compress anymore.. the action faded over a few months.
I tried to change the tubes and even exchanged the opto cell with the other LA-610 and it did no good.

So I guess a cap or a resistor failed.. I'd need some guidance and some precise schematics

Thanks in advance.

Presonus Firestudio Project - Needs power supply schematic

Asking on behalf of a fellow member on another electronics repair forum. He seems to have a bad a resistor that is some type of 1/4 resistor that is right beside the bridge rectifier. Obviously, these new types of schematics are tough to come by... However, the year of the device is 2007 and all that is really needed is the value of this resistor. Just checking as I am curious if anyone has come across any schematics like this one in particular. thanks. thumb

Amek 9098 Dual Mic Pre schematics (AMEK 9098 DMA) Schematics looking for

Hi all ! does somebody have the Amek 9098 Dual Mic Pre schematics (AMEK 9098 DMA)
(without EQ ).

The Rack have not EQ but have a DI INPUT, I know the schematics is a little bit different.

Thanks for your help.

Please if you can mail me at this address if you have it :

Thanks by advance.


Sound Master STIX 305 schematic request

Strange one this-All the digital chips (4011's, counters, RAM,etc,) have the correct power going to them, yet the 7555 counter/comparator strange shit, dont know what it does chip, only has 3v. Should work between 5-12v. replace all electrolytics-NADA
Anyone have the schematic please
I have plenty of swaps for vintage gear

Cheers all
