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... -
Hi Guys
I have a customer who has two Hitachi TVs in his bar, one is the model in the thread title and the other is a larger screen but has the same setup menu
He also has an LG TV, so three screens in the bar
I installed three Satlink ST-6503 DVB-T Modulators
This model https://www.aliexpress.com/item/32916553905.html
These connect to three satellite receivers via HDMI cables and then connect to a 4 way RF Amp that connects to the TVs on aerial cable. There is no incoming terrestrial antenna. I set the channel ID on the modulators to... -
Hi guys,
I need a help with my Marantz pm6005. It started to have weaker the right channel a few months ago, than it got back to normal and now it has lost sound completely on the right channel. At the final stage it was loosing the channel for a while and than it returned. After it has disappeared completely I could forced it back by unplugging the source form CD (which I normally use) to phone and back. It would then work for a few minutes and died again. Now it is possible power up and all function works normally (apart the right channel ) on all inputs, except the phone both channel...01-30-2023, 12:11 PM -
So my dilemma is that I can't seem to get my board to run in Quad Channel. I have an X10DAX with Dual E5 2690 v3's and originally it had four 16GB sticks of Samsung ECC. Figuring I needed to have a stick for each DIMM1 slot I purchased four more identical sticks of Samsung M393A2G40DB0-CPB. So, now I have eight 16GB sticks for a total of 128GB of RAM. When I install the ram so that Each DIMM1 slots is populated the system will not post even if I clear the CMOS, remove the battery, what-have-you. But according to what I'm reading in the Manual, which is admittedly not very clear, populating each...

I am working on repairing a 1970s Magnavox stereo console. The Left channel works perfect, but the right channel is dead at the speaker. This happens in all modes (Tape, Phono, FM Stereo). Now, I do have audio from the right channel via the "Tape Record" output, so this confirms the problem is in the right channel AF and Output amp? I also tested the speaker itself. I attached a schematic of the Right channel: AF and Output.
In addition to a recap, I found that R101 and R107 were both open (see arrows). I replaced R101 and R107, but they both become very hot....
