So I have tested the HV output using my new Fluke 80K-40 probe (1000:1) into my Fluke DVM. First I set the meter the AC and used the Probe to measure the line input voltage (240V / 50Hz for me). The meter display 0.244V so a good 244V which is fairly typical. I then moved the meter to DC Volts...

Happy days we are going to have some fun over the coming days….. Fluke 80K-40 high voltage probe.

Hello I think I purchased the speakers around 1998, the serial numbers can be seen on the frequency plots But are SEJE464 and 465 Hopefully the panels will be OK once I get to testing the HT PSU as this is where I fancy the issue is still. Thanks for the great feedback

Thanks this is on my hit list to check after verifying the HT output once I get my probe (which has now shipped)

Hello all, I did reach out to ML and Brian Bailey suggested a few things I will try. Here is Brian’s suggestions Generally, you have one of 3 things happening: 1) Bad internal HV power supply not putting out the correct voltage 2) Loose connection of the stat wires on the panel 3) Bad panel...

Hi There ! I also have a classic Linn system, LP12 Sondek / Ittok arm (various cartridges, but a Koetsu Black K currently set up). The LP12 has been constantly upgraded over the last 25 years. Not many thing you can say of that. Amps and speakers were the classic Naim and Linn Isobariks now...

Many thanks Russ, So I have ordered a 40kV probe for my multimeter. As I have a Fkuke DVM, I ordered the Fluke probe. This should be with me in a week or so. eBay seller in the USA, so international shipping, taxes and duty to pay for when it arrives, but still less than 1/2 the price of new...

Hello everyone, looking for some help on my much loved SL3's that are not as happy as they once were. The left hand channel lost output, and I have ventured to opening the back cover and looking at the PCB. I could see that the high voltage multipler had failed by the toasty components. I...
