Rich, that looks fantastic!!!!!! Bravo!
Are those wooden knobs? Beautiful!
What are you powering it with currently?
Any issues with the Pearl through the B1?

Thank you .... the knobs are aluminium .
I'm using a regulated PSU from a door entry system that I had kicking around .
17.71 VDC .
The sound of the pearl is not great , I have my phone on the other input for comparison and it sounds much .much better .??????

Lol... I'm saying don't worry about it. Caps don't make anywhere near as much difference as people like to think they do. Use whatever nice film cap you can get of the proper rating and voltage. Get the circuit working. Listen to how good it is. (And it is quite fantastic 🙂 )
Then, if you want to mess with it, spend a ton of money on whatever audiophile approved caps you want and then see what kind of difference they make.

If you are talking about the 10uF caps I believe the original used axon's. Partsconnexion don't stock the 10uF size but do have 11uF which I think should work fine. cheap too. AXON True Cap Metallized Polypropylene Capacitors at only $2.88 each 🙂
if you are only buying two they should come in well within the 250g Canada post small parcel Limit which is about $10 from memory for shipping. Bit steep paying $10 in shipping for $6 worth of caps I guess, but that's the way it goes sometimes!

Output caps does make a difference in B1.I have replaced AXON true caps with cheap Russion K73-16 caps 12x 10uF 63V PETP K73 16 Capacitors | eBay
Believe me there is a great improvement in SQ.

When I go on the water, I wear Musto(&Hyde) clothing : hollow polypropylene fiber underwear, and breathing ptfe membrane outerwear.
Only downside is that a complete outfit costs several thousand dollars.
If you favor all-polyester at 75 cents/per, be my guest.
Believe me, if 9101 means Januari 1991, you live in the previous century.

Yes I do favour 75 cents/per Polyester over some expensive PP caps.Try it to believe it.There are also few threads here suggesting the same http://www.diyaudio.com/forums/parts/143675-petp-capacitors-one-best.html

If I were a believer, I'd walk barefoot and hit myself with a branch.
PET is PET, I only swallow that from a bottle.

Papa Pass himself suggested in B1 artical that Polyester would be just fine.They sounded better than AXON PP caps in my B1.

I worked as a QC/QA stiff on the first Coke PET-bottle production line here.
Seemed like the best next thing.
(in particular if one previously did the same at the end of a 150ft rolling "doormat" Glass line, at +40C )
Nowadays, one is lucky to get it in a glass bottle, and Classic Coke doesn't even taste classic to me.
The B1 sounds like the next best thing to you.
Me, I've built every possible buffer 20 years ago, from Burr Brown OPA dip8 ones to full discrete, as (balanced) line drivers.
You can do me a favor by sawing a Ruskie in half, and tell me what you see.
Mentioning that you enjoy Coke Classic in a PET bottle doesn't really cut it for me.
YMMV, regards.

Can you get the Made in Mexico Coca-Cola in Holland or (probably easier) Curacao? It's the real stuff -- Amazing!
Coke changed (for the worse) in the USA in 1984, and the Mexican Coke tastes like when I was a child.
Manufactured locally, at both locations (on the island, right next to the biggest supermarket).
(Camel cigarettes are manufactured under license locally as well. Difference between a 20-night stand with a 20-year old Raquel Welch, and a $20 chick with a stick)

Bummer. The Mexican stuff is really unique. Glass bottles as well.
Come to Burning Amp, it's available in the US with only a little searching.

You wish me to risk my life every year at BA, by flying over with Pèpè Gonzalez ?
Shopping at latino shops in Castro is fun, lots of nice items there to stuff in a flightcase.
With my shirt off, I likely wouldn't look suspicious at the Folsom street fair, if not for showing signs of arousal by various leather dikes.
(you should try driving up and down the Panamericana from panamÁ city, with a Puerto-Rican fool, a handgun between his legs, one under the seat, and another in the glove compartment)

2x12v sla
Hi everyone, I was hoping someone here could clarify if I would be able to use 2 x 12v sla batteries in series as 24v to power the b1 buffer. In the description it says 18-24v but since the fully charged batteries output a bit more than that, will it still be fine?
Thanks for your help!

Another question I ran into is regarding the 1uf and 10uf caps, how important is the voltage rating here, I see some use 1uf and 10uf 400vdc, but would it be fine to use 1uf and 10uf 200vcd?
Thanks for any help... I'm really starting from scratch here so pardon the possibly ridicules questions.

If the worst case battery voltage is 13.8Vdc and you have two connected in series, then the capacitor voltage rating never needs to be above 35V. 25V rating might work in all locations but there may be a few location that could just exceed that lowish rating in exceptional operation.
