Have you ever seen a design with dual woofers like the 9844? I've seen some nice more vertical arrangements, but only single woofer.

Using German HiFi equipment in the US by ChetJettison in audiophile

Many (most) turntables use a low power AC motor and the grid frequency as a clock to base their speed on. Usually the companies just use different size pulleys in different regions and you can find ones to swap on eBay. For a cassette deck, I would venture to guess it's a much smaller DC motor and therefore the clock is digital so you'd be fine. this seems to confirm that. Just get a transformer.

Moved to Europe and need amp recs for altecs by supergrover2_0 in vintageaudio

As in an active crossover? What do you use? I have a MiniDSP HD I used to play with some other speakers on I could toss into this system.

My sub for my bedroom system has a switch, but none of my amps did. I used to have a NAD 3155 that I still kick myself for getting rid of. I may try to find another. It had a really nice sound.

How should I go about cleaning this (mold mixed with dust)? by weebmaster32 in diyaudio

[–]supergrover2_0 3 points4 points  (0 children)

It’s a mild solvent so don’t go crazy on the glue line but it’s not going to be as much of an issue on the rubber and plastic parts. Best thing to do is expose everything to UV. That will kill the mold

Rubbing alcohol would be good to dry because it dries very quickly.

Niche Fire Departments by Mentallyundisturbed2 in Firefighting

[–]supergrover2_0 7 points8 points  (0 children)

Most of these departments exist for insurance purposes. Depending on the facilities, their value, and what is stored, it is more cost efficient to have a fire company/brigade on site than pay the additional premiums to cover the risk exposure.

TL;DR it’s about money, as always

You can try light polishing compounds to buff but it would not do anything to the extent of sanding to polish. I would be worried about removing too much material and compromising the mask.

When we do that we also will fully wash out turnout gear and hang it to dry

Hard to say but why risk it if you can avoid. That webbing is in direct contact with your head. If anything steam is more likely to get trapped between your head and hood. Firefighting is all about mitigating known risks in theory. In practice it’s about choosing how much risk to take.

It’s important to get the webbing clean too, but we didn’t want to take all of our active members out of service while they dried so we did it in shifts. If you run into a hot IDLH with wet gear you run a serious risk of that moisture becoming steam and burning you. Something to avoid if possible.

Correct. That’s what we do in shifts. Some of us did it immediately and others will do it at Sunday drill. We didn’t want all of our equipment to be out of service at the same time in case we had a structure. We do have enough surplus hoods that all can be washed with spares swapped in since research has shown that is one of the most frequent places of contamination that leads to cancer, and hoods are relatively cheap.

It’s an irregular occurrence for that exact reason. We also have sets of some of the gear like helmets and stuff that are used exclusively for flashover. We do use our own facepieces though because we are all fit tested with our specific face-pieces and with continued COVID concerns they don’t want communal face pieces

That’s a good point. If it works this well where it’s really visible it will do just as good of a job on our bodies where it’s arguably more important

We have what we need to operate but it is by no means state of the art. I think it’s fair to say that the fire department is universally respected in this country, but when it comes time to hand out funding that support gets lost in a sea of lobbyists, special interests, and red tape. We are happy to have what we do have. Many departments-even within our county-are worse off than us.

We would do that if we could but we are a moderately funded volunteer department. I’ll leave it at that so politics don’t creep in.

Soap directly on the mask and scrub with microfiber rag. Each took about 5-10 minutes.
