That green double vinyl is War On Drugs 'A Deeper Understanding' special edition version. Cost me a week's breakfast.

Finn doesn't understand why I'm so preoccupied with my music so he just sits there and stare at me.

Is that Finn (number FN-2187) from Amp Wars: The Last Triode? :ksc75smile:

The day I got my Rega RP8 home 3 months after I got Yggdrasil and find it more resolving and more musical, that's the day I cross to the dark side and Finn could well be the last doggy. :)

Some work involved to keep the vinyl pops and crackles free. I have an Ultra Sonic Cleaning machine and a vacuum cleaner. This 2 stage process works wonders. :)

Very interesting! I just checked out that ultrasonic cleaner. Very cheap - especially compared to other ones I've seen. I use two spin clean record washers (one to wash, one to rinse) and then a VPI HW-17 for a final vacuum rinse. I'm going to have to try one of these ultra sonic cleaning machines.

Which do you use first? Ultra sonic or vacuum? If I get one of these ultra sonics, perhaps I could also use it with the HW-17. edit: Ok I see - vacuum after ultra sonic.

Listening with headphones, I'm very particular about the vinyl I listen to. It must be in as new shape and very clean.

Leftside ! :)

I use Ultra Sonic first (up to 6 LPs at a time), then the Record Doctor V to vacuum. Your VPI HW-17 should do a good job of vacuuming it dry too.

This is where I buy my USM from Poland. I got the cheaper model that does not heat the water. There is a higher grade model that does. A temp of 40c is ideal.

I use a tablespoon of Triton X-100 solution mix into the one tub of water.

I bought this to heat the water manually. :)

and this to test the water temp.... :) Pretty hi-tech huh?

Yes agreed.

I've done some investigating:

https://www.ebay.ca/itm/New-Stainle...ltrasonic-Cleaner-Heater-w-Timer/322321184009

Looks like I can combine all 3 cleaning methods(!)
"I now use a Chinese 10L US cleaner and a Vinyl Stack. My process:
Spin Clean, as a pre cleaner to dislodge most of the dirt etc on the LP, blot dry.
US clean using Rushton's formula, at 1/3 rpm / 5 rev in 15min.
Rinse.
Nitty Gritty vacuum dry. Then inserted into a new MoFi inner sleeve.
I change all fluids after 20 LPs."

You are doing it right. Wash, rinse and vacuum. All 3 steps are vital. I need another tub for the rinse. :) Of course use MoFi inner sleeve. After all that trouble your want the best anti-static sleeve.

I'm listening to my cleaned LPs from several weeks ago. On a headphone such as the HD800, it's pure bliss. Speakers too. All the details and absence of pops and crackles.

Since we are talking rectifiers. This arrived from Santa today.






Sounds great...really nice imaging and sweet mids.

Glenn, is the voltage drop for this 350 ?
Click to expand...

The voltage drop is 50 at 125ma current draw. The amp will draw only about 100ma max so this voltage drop will be less.
It might actually be running the EL3Ns more properly. The EL3Ns were used with a wimpier AZ1.
Originally I made the first amp using the AZ1 but people wanted to use 8pin 5volt rectifiers.
