| Voltage conversion of Accuphase E-650 @dbxdx5 While it is not necessary to bias the power amplifier after voltage conversion, I thought it would be a good idea to record the rail and bias voltages before conversion for future reference. | |
| Voltage conversion of Accuphase E-650 @dbxdx5 Yes, switch the voltage from 100V to 120V, leave jumpers J1 and J3 unchanged. | |

| Audible Illusions Modulus 2C Tape Out? Unless the source is a turntable connected to the AI 2C phono input, most preamp circuits simply loop the line-level input signal to the tape output. Of course, there are exceptions to using active buffers, but I doubt that's the case with AI 2C... | |
| Voltage conversion of Accuphase A-65 or A-70 @foolishman Just wanted to let you know that I don't have any experience with A-80 voltage conversion, I'm just making recommendations based on photos and previous experience converting Accuphase amplifiers. I highly recommend using DBT to power... | |
| Voltage conversion of Accuphase A-65 or A-70 @foolishman Thanks for posting photos of Accuphase A-80. To convert the mains supply voltage from 100V to 120V, my suggestion is power up the A-80 with 100V mains, Use an AC voltmeter to measure the voltage between the yellow/brown and red/bl... | |

| how to run three subs from one lfe jack Rolls DA134 Line distribution amplifier SPECIFICATIONS The DA134 is a four channel RCA distribution amplifier with RCA and 1/8” inputs that can be switched from mono or stereo. The DA134 Distribution Amplifier will distribute a mono signal to eig... | |
| Magnavox 196 197 amplifier balance pot removal/bypass help please If your device same as the schematic below, you can connect a 500k resistor to each channel to replace the balance pot. Magnavox 196 re-build | |
| Parasound HCA-1000A Modifications I am assuming that TRV101 and TRV 201 are for setting the bias voltage. Yes. What is the other (TRV102 and TRV202) used? The pots for fine adjustment bias. https://www.diyaudio.com/community/threads/parasound-hca-1000a-bias-circuit | |
| Voltage conversion of Accuphase E-5000 @foolishman Sorry, I have no experience with voltage conversion with the Accuphase C-47 and PS-1250 either. I'd love to know how to do that though! If you could provide some close-up pictures of both sides of the power supply board in your thre... | |
| Can an owner's manual and schematic be found for an Electron Kinetics eagle 7a power amp The schematic https://www.diyaudio/threads/electron-kinetics-eagle-7a-amp-help. I hope you may find it useful. | |

| Voltage conversion of Accuphase E-5000 @foolishman Thank you for the photo. I think the voltage conversion can be done in the PCB on the left, can you post an image of the front and back of that PCB? | |
| Modifying a Coincident Dynamo Mk1 https://ibb.co/R7YJVdg I can't tell from the picture above whether the two 47uF 400V capacitors are connected in parallel or in series. I could be wrong, but it looks like the two large 1000uF 315V capacitors are in series with a 100KΩ balanci... |
