what to keep analoge system perfect working?

Hi,

the intent of this thread is to expand a bit more the subject on how to set the cartridge, keep it cleaned and keep your LPs in a good shape.

I came out with the following list of tools:

1) strobe disk to fine tune the speed, wherever it is possible to do so.
I was thinking of K-A-B Strobe disk that seems to be a very precise tool

2) clean off dust from the records.
At first I was impressed by the Nagaoka roller, but after researches I found it not to be as good as I though and all in all the carbon fiber brush seems to be still the classic solution for dust

3) vinyl cleaning machine.
There are several solutions out there but they are pretty expensive.
I found a DIYs to be much cheaper but yet as efficient. It just needs an old TT and a wet/dry vacuum;

3a) for the liquid fluid a diy version should work fine. Unfotunately the fluids on the market are quite of expensive and if you have a wide selection I guess this is the way to go:
- 3 parts of distilled water
- 1 part of Isopropyl alcohol
- few drops of photographic wetting agent

3b) brush for the cleaning duty.
To spread the liquid, it is supposedly better to spend few more bucks and get the VPI HW-17/17F brush than having a cheaper solution that won't least as long will start shading soon and won't be as efficient

4) keep stylus clean.
I found a very inexpensive solution for it. It is called Mr. Eraser ME. It seems to have gathered a lot of follower among all the people that have been using it for long time

5) perform cartridge alignment.
I found Mint LP to be the best custom made tool. Unfortunately it is costly. (does it also have a mirror to check the azimuth?!)

6) digital stylus force gauge

7) level to check if the platter is flat

This is what my understanding of what's needed for a perfect analogue front end set up and maintenance till now.

Please feel free to comment each point and give suggestions.

Best,
Stefano.

Re: cleaning solutions, many here like steaming. I've tried it and it didn't work very well for me. I've found nothing better than the enzyme-based solutions from AIVS (or Walker or MoFi). But they are expensive and slow to use.

Your DIY solution and good vacuuming should get the record clean enough so it won't be damaged during play. If there's any trace of residue it'll cling to the stylus. The ME will remove it if used regularly.

Your vacuum device sounds like a manual/DIY version of my Loricraft or a Keith Monks. (Scroll down 1-2 pages to the section "How is the Loricraft different".) Great idea!

Those machines use a thread to maintain a tiny gap between vacuum nozzle and vinyl surface (check the closeup pictures). The thread is advanced a few mm after each sweep so the bit touching the LP is always clean.

I think you need something like this to avoid having your tube opening making a seal with the LP. That could scratch the record.

Without seeing your DIY device it's hard to say what the best material would be. Thread? String? A bit of soft cloth? Whatever you use, change it frequently to prevent contamination.

Keep on thinking, you're doing some good stuff.

thank you very much for your response.
I will try some improvements soon to see how it works.
Unfortunately the vacuum just smoked last night and I don't why since it was supposedly a wet/dry type.
I will proabably use a normal vacuum and a bottle for recupation of the liquid part.

Thank you again Doug, your post are always high content!

I will post again when modifications to the maschine have been made.

There is lots of information and opinions re: record cleaning fluids. IMHO the claims are largely exaggerated - most of them seem to work fine, more or less.

I do not have a problem w/ IPA in the RCM solution; it does seem to help with certain kinds of gunk.

But I do think that the key is to use clean (denatured or RO) water as a first and *most importantly* last wash or rinse.

I didn't do the rinsing part. I was assuming that washing with the solution and vacuuming would be enough.

Perhaps I will add the rinsing step with distilled water and than vacuuming again.

Sorry just one consideration/question.
I have tried to put two holes on a jar to attempt to separate liquid when sucking it off the vinyl to prevent damages to the vacuum.
Apparently it looks like the vacuum is still sucking the liquid off (part is being deposited on the jar and a good amount is still sucked off from the vacuum).
Do you guys know if there is anything (size of the tubins, lenght) I should be awared of?
More to discover
