          Never seen one of these before but it's a Small amp manufactured by PS Audio.

          I believe the model is SPR-A1

          Known as the Sprout.

          Apart from that i literally cannot find any other info on this thing.

              compare signals for each channel and see where it stops .. you will need data sheets for the ic.s first .

                  I guess it would help if we could see the boards first place?!

                      R333 (3R9) O/C

                      Suspect it has been taken out by IC302 which i need help to identify.

                      It's marked Abletec.com C1 & below that is 306P

                          Swap the good IC where the bad IC was, fix the resistor and see what happens.

                          Edit: plenty of abletec.com C1 on AliExpress.

                              Hi,don't want to cause more damage as components around the suspected faulty chip blown.

                              Ordered a chip from Ali , but not sure if the 306P marking has any significance , or is some sort of batch code.

                                  American Audio VLP1500 Distorting on one channel
                                  by dicky96
                                  Hi guys I have a VLP1500 amplifier here - one channels works fine and the other channel distorts even at low volume settings

                                  Protection and Clip LED are off

                                  There is something wrong with the BIAS voltages around T16 and T18 (in particular) on the bad channel

                                  I tested all diodes and transistors in this area in circuit with diode mode - both channels seem identical. Same in resistance mode across all the resistors here.

                                  The output DC voltages on pin1 and pin8 of the 5532D dual op amp at the input of each amplifier module are the same, and the audio...

                                  Really strange one. Got this amp with digital noise coming from all channels. BAD cap on 12V rail and burned via on -12V rail causing -7V and +7V rails missing, audio noise and "SP CONFIG" message (thinking that MIC is plugged in then it is NOT, but before I replaced cap and fixed rails I have accidently left it ON with output transistors for rear channels hanging in air (NOT HEATSINK ). One channel blew. After further inspection found a LOT of caps out of range on DSP and Processor boards. Replaced every single one that did not pass my ESR test(almost all).Got receiver back together...

                                  old X58 triple channel board... memtest86 memory speed?
                                  by eccerr0r
                                  Anyone run memory speed tests with an old X58-based triple channel 1st gen or any other >2 channel board? The one I have is a Gigabyte I think.

                                  Anyway I had four 4GB DDR3-1333 modules in the 6 memory slots and got around 11GB/sec memory speeds assuming that it went dual channel since it didn't have enough modules for triple channel. Now I stuck in two more 4GB modules, but they are DDR3-1600. I'm still getting 11GB/sec speeds according to memtest86...

                                  Just wondering, anyone do memory speed analysis on these triple (and higher) channel memory boards? Are there any...

                                  Reverse engineering of 18650 4-channel tester
                                  by spleenharvester
                                  Hi friends

                                  I have reverse engineered this tester, schematic is attached and is complete except for capacitor values. These testers annoyingly have no model number but they are the ones you find on the first page of just about any website if you type in "18650 4-channel tester". There is also a 2-channel variant and a newer 8-channel variant. They are very cheap (about £15) and can measure voltage, current, internal resistance and capacity. They have a multicolour display for all these statistics. They also have terminal blocks so that if you want to use a breakout board...

                                  Lantec PULSE 386 subwoofer - no audio output
                                  by kotel studios
                                  Hi

                                  I have this Lantec PULSE 386 subwoofer I got a while back laying around awating repair for quite some time. Sadly it's missing it's original speakers which it came with.
                                  After plugging in the mains, the LED on the volume controller lights up. When I plug in the 3.5" jack cable to my soundcard (confirmed to work), I get no audio on the subwoofer (nor the speaker jack at the back).

                                  The PCB is quite simple. There is a UTC4558 amp and two D6282 audio amps. When I put my finger on the UTC4558 I can see and hear the speaker "fart". Although, the left...
