Quick reply. Would the ultimate turntable also take into account mis-centred records like the Nakamichi TX-1000?Remember it had a sensor arm that rose up out of the chassis to read how far 'out' the centre of the record was.I had one...nice to watch....

It is already converted to the fixed bias on the second stage with 47K and 10 voltage divider from negative filament (positive filament is in ground) and I have the perfect 150V on the second plate. It is already fully operational with 8mV noise not ...

Was talking with various audio people about the 6C33C I was amazed that people are so clueless about this tube. The people are so filled with some foolish prejudges and faulty notions about 6C33C that I deseeded to put together a brief “6C33C user ma...

There was a conversation about the Melquiades meters in past:

However, I have a concern about what you do. You are trying to come up with chassis or an idea of better parts for Milq but you have no...

Thanks, LBJ
It is useful. I had also an idea to have a port mounted on removable plate in order to have the port side changed. I also, very much inclined for the yellow version, even my reasons are very none objective and I based my superstitions on...

Doug, it is a lot of tuner went over your hand. I wonder what drove you to do so. Was any specific quality of sound that you were looking and the tuner that you own did not serve you?

Hi Romy: I did not find any computer-based HD Radio receivers. The following link to HD Radio receiver Manufacturers does not seem to list any IT firms: http://www.ibiquity.com/manufacturers/receiver_manufacturers So, I spent some time researching H...

[quote user="Thorsten"]If you do, do seek out old Air dielectric AM tuning Capacitors. You only need 110pF & 330pF, both can be found suitably. Once you tuned the RIAA to perfection simply superglue the shaft in.... I used to use that trick in pr...

[quote user="dazzdax"] Sakuma's idiosyncratic and esoteric way of thinking (he believes for example that tubes have a "soul") is not to everyone's liking. He is projecting his mind into a sort of tone control. At least for him this tone control bring...

I must say that I have always thought the Cardas "Golden Ratio" schtick was pretty lame. So it was with no small measure of trepidation that I sent off a rather outlandish sum of money for two Cardas Golden Whatever 4.7 uF caps for th...

It's 60Hz hum, caused by both mechanical and magnetic field coupling to the output transformer. I used a toroidal transformer and thought it would not caused this problem but it did. When using an external power supply for both ...

...this is my first serious attempt to pack something into a case.[quote user="Paul S"]Nice looking unit, N-set. I also go out of my way to use part leads only in lieu of extra wire whenever possible. I really don't care what it "looks like" on thi...

[quote user="Paul S"]If you can do it, try isolating both cases/chasses from your "ground plane(s)". Use one inclusive "ground plane" for both the PS and the gain/RIAA sections, and ground this "ground plane" to the house "neutral" wire. Do NOT conne...

[quote user="haralanov"] Also instead of using electrical tape, try to seal the back of the driver with a 2mm thick sheet of microperforated tonewood and then glue a leather layer over it. Then you could also pierce multiple tiny holes in the leather...

What you guys are missing is a grand scale of the concept. You are talking about voltages, implementation, electric chairs and the rest of irrelevant crap but I am talking about the pure inspiration from the concept. No one runs to solder anything. I...

Bill, when you were at my place I use two PP2000 running together as at that time I did not discover the effect. I was running my MF at -2dB and my tweeter at -1.5dB. As now I use one unit and I return back my MF and HF channels to the level as they ...

That was the 4 way system designed by John Sheerin using GOTO drivers on my request. The tweeter is GOTO 160 with S3000 horn xover at 5kHz. The high mid is GOTO SG370DX with S600 horn xover at 1kHz-5kHz. The low mid is GOTO 505TT with S150 hor...

Romy, Selling the heavy stuff would be smart... Wait a minute; its all heavy. The ULF modules would be fairly easy to recreate; in any case, I want to redo the enclosures using different materials, so this part of it makes sense to me. I'm not ent...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

I got a forwarded email today containing the Lamm Industry’s release notes about their new SET amplifiers.

From the point of view of a methodological purity indeed the location of a vacuum

After eons of construction, I've finally completed my version of the 801A premap, based on Ale Moglia /Bartola Valves design with his Gyrator anode loads, SiC bias and Rod Coleman filament supplies. 6 inputs, switched by an Elma switch and Dave S...

Jarek, because the PP introduces different grounding schema into your system I did suggest earlier that the phono may require alteration to suit. In my case, when the grounding schema was altered, one phono had a similar issue to yours and the s...

Anthony and Romy, thanks for taking the time to respond to my question. I want to take on this project as a learning experience both in terms of simply building an amplifier from a schematic and for my edification on sound reproduction.

Hey, people chill out. The guy provide just information, I do not think he makes any adjudication comments and if he would then why not. For sure the TG Lee Audio generator does look interesting. The separation of the chasses on 3 sections is very ri...

The Rockports have a very light platter and a carbon Arm....the one I listened to was the latest, it had simply no Bass reproduction, nada, nothing and the Arm resonances are also inferior to any energy transfer from any cartridge. The lead wires are...

I was replacing transformers in the Super Milq HF channels and while I was doing it I decided to perform a minor maintenance on the amp. One of the amp’s fans developed a “flat” in it bearing and created a very minor “step”. I order a replaceme...
