i like your reasoning! makes me wonder why on earth i just bought one lol with that said if its anything like his phono stage it will be worth it.
The VAS is a good phonostage isnt it. I thoroughly enjoyed it. by all accounts yes,once the lock down ends im planing to visit and hear it. |

Must admit, I wouldn't bother with something like this myself. See little point in having the provision for 23/64 levels of attenuation, when most would never get used. My normal listening level is sort of constant. Having 3/4 levels of attenuation in reserve would be enough. I'd just wire a switch gang for 4 levels and spend the money on the 16 resistors that would actually get used. i like your reasoning! makes me wonder why on earth i just bought one lol with that said if its anything like his phono stage it will be worth it.
I'm all for logic and simplicity. |

help oli! how did you wire up your attenuator? i think im doing something wrong as im getting massive hum with no volume control up or down. ist pic is the wiring diagram i got from stoyan,2nd pic is how ive wired it. im sure the 2 ins that go from the line selector (blue and yellow) switch should not be together? ditto on the 2 outs.(black and red)
on the gold point each pcb has 1 in and one out. on this attenuator there is only 1 tag per pcb?

Come to the font of knowledge.
The two tags are the outputs where you have wired blue/yellow and red/black.
Underneath each tag (to the left on the photo) are two positions where the resistors have been soldered.
The one next to the 8K06 resistor is the input terminal, shared by the resistor.
The one next to the 14R7 resistor is the ground terminal, shared by the resistor.
Now the diagram should make sense. Shout if you need more help.

He came to this "droplet of knowledge" via phone call lol I call it the "trickle down"effect. I buy one, cant figure it out, ask you. Jamie buys one, cant figure itbout, asks me lol |

Erm.....got an overview pic of your amplifier? Doesn't look to be much space |

yes it will fit just,hassle though to do it hence why its gerry rigged to see what its like first.another job for the bloody lathe i think.  |

What's your initial impression? well there would appear to be a touch more openness to the top end,a bit more detail perhaps. considering the goldpoint was £200 odd its certainly not worse for sure.

i have noticed that on one step there is a lot of hum. Oooh, I had a loud pop on mine for a few days in the first couple of steps. It has since dissapeared. I stood there for a few minutes just twisting the contacts back and forth every time i switched the system on or off. Seems to have done the trick. You may need the body grounded, if you havent done so already. Thats the lug at the arse end BTW |

YES...the "bit more detail" threw me. I thought i was imagining it but the more i listened the more it became apparent that i wasnt. Excellent. |

Don't want you to have to clean up dog mess every time you listen to your music. |

A couple few weeks back i agreed to take on a Bigbottle build. It's been a tough one as delivery delays and the timescale involved has made it drag on a bit. The case still isn't here, and through my own stupid fault i may have inadvertently discovered that EI transformers used in a separate box may actually be the best way to elevate this phonostage to peak levels on the topic of what transformer to use with it.
But lets rewind to the first question most people ask me when they build or buy a Bigbottle Phono....."What Valves do you use/recommend?"
The answer is always the same, Telefunkens! Well, actually this time it was a little different. The ECC83 is a GE Milspec and its a phenomenal valve, but id snatch your hand off at a Telefunken.
A couple of days later, bigbird had ordered his trio of Telefunkens....well not quite. He had a bonafide Telefunken ECC83 and 2x Telefunken branded Siemans-Haske valves on their way to me. I was worried that they wouldn't be up to scratch.....WRONG!
I gave the PCC88's a listen for 5 minutes with my GE valve and then ordered myself 2x of the same Sieman- Haske Telefunkens
It was such a great sound.
Then the ECC83 turned up.....my god.....its such a great valve. Honestly. I would not hesitate to buy one but the bank said no. Sadly.
So today the Postie dropped in my PCC88's.....and here is where it gets interesting.
I gave all four PCC88's a quick listen just to see if they were working ok. I didnt want to leave them weeks in case there was problem. I put all four on the side and picked up the first two.....very nice i thought.
Next two....what the F#ck? They were so holographic and spacious sounding. I switched back...ok, they were fantastic, holographic and sweet. I swapped in the other two and again, i was standing there with the hairs on my neck on end....WHAT IS HAPPENING?
I took the valves out of the phonostage and had a look at them.
The factory codes and the batch numbers were exactly the same, Possibly even traceable to a single employee at the time they were made (around 1968ish) according to the info online!
See here:
The first 2 that turned up were from the same factory but were "6" and "1" which i believe are the batch numbers.
Next two were "10" and "1" with "10" being from a different Factory and "1" being from the same factory as "6" and "1"
I had accidentally picked up the two "1" valves and put them in together. These two valves have a synergy or something because together they sound utterly mesmerising. I then put the ECC83 in.....shouldn't have....lol My bank won't allow another valve purchase and now im sad lol
Anyway, how magnificently freaky and almost fateful that these two valves should show up at my house and be reunited in the very first "commissioned" Bigbottle Phonostage.

Do you really want to go totally solid state when valves can sound this amazing? |

Thisbis a cracking listen....a bit...weird in places, butbi have thoroughly enjoyed it. Also, the recording is stunningly good. A future must have evaluation LP. Brilliant. Great recommendation bigbird  |

No they are not. You have got red and white mixed in rows and/or columns.
That doesn't make sense.
