    Simple Attenuators - Design And Testing

    I spent a little time trying to figure out how to mount the inductor too. Some inductors already come with non-metallic supports. I’ve seen some in spindles. Some others already come with zip ties from the factory. The Dayton brand inductor I used came with two zip ties. I added two more zip...

    Simple Attenuators - Design And Testing

    Thanks @Gene Ballzz and @JohnH for answering my questions yesterday. I was able to finish mounting all the components and wiring it up. I have the switchable stages set up as -14, -7, and -3.5 dB. I added an additional fixed -7dB stage before the switchable stages. I only got to play through the...

    Simple Attenuators - Design And Testing

    I have a question about the order of the stages in the M2 design. Is the input/output impedance relationship not maintained if the resistive 7dB and 14dB stages (2 and 3) are swapped in order and both are engaged? I came across some posts early on in the thread that alluded to electrical reasons...

    Simple Attenuators - Design And Testing

    I am using Carling 2FB53-73 SPDT On-On switches. I was originally only using the drawing to lay out components as they will be oriented. I quickly added some wiring afterwards, so I’ll have a visual reference to keep track of my wiring. I do see how it looks a bit incomplete without a good view...

    Simple Attenuators - Design And Testing

    Thanks @JohnH and @diego_cl . It’s been very helpful to get some advice. The video was the perfect visual aid. I just mounted a few of the smaller 25W resistors after absorbing the feedback. I’ll move onto the larger resistors when I get the time.

    Simple Attenuators - Design And Testing

    Thanks. I was trying to Google general tips on applying the paste and was having no luck. I'll need to make some cut outs that are the same sizes as these resistors and experiment with the amount. I 've got the chassis all drilled out already. I need to double check my planned wiring before I...

    Simple Attenuators - Design And Testing

    I am finally going to build an attenuator based on the 50W M2 design after a long bout of procrastination. I will be using 100W, 50W, and 25W Arcol resistors. Do you guys have any tips on applying the optimal amount of thermal paste onto resistors? I’ve only ever used thermal paste on older PC...

    Simple Attenuators - Design And Testing

    I recently heard about the attenuator projects in this thread and am looking into building an M2 attenuator in a Hammond 12"x8"x2" enclosure. I was jumping around the thread to absorb as much information as possible. Could anyone comment on the apparent listening levels of 31.5dB of attenuation...
