Some Pics To Peep...

[tommytones]

I haven't contributed much lately so I thought I'd show a few of the things I've managed to put together along the way.

SL-9K pre (2 channels on 1 pc)

This a little output amp which is going to follow the above 9K pre's. These are actually going to be used for the output of some racked Neve 5100 modules I'm putting together for a friend of mine but I have another pcb waiting for me.

Cool stuff. The orange transformers look like evil mushrooms.

Looks great. I love toroids on PCBs :green:

Best regards,

I notice that on your 9K boards that you have what looks like resistors where the wire links go. Are these zero ohm links & is there a reason behind this ?

 

[tommytones]

I prefer using 0 ohms for a cleaner look.

 

[Mbira]

Looks great Tom! Do you have your PCB's made just as one offs, or do you have to make a bunch at a time?

Here`s a couple of questions that I`ve asked before but not had much response.

1. What value are Cx?
2. What value areC74 & C47?
3. I can`t seem to find C63 on the diagram so what value is that also?

Alright so there were 3 questions, I lied!

Anyhow if anyone knows this info please can they tell me beacause I want to get these mic amps finished ASAP.

 

[tommytones]

Sometimes 1 offs sometimes bunches...

Cx is 0.1uF film

C74 +C47 3.3pF ceramic

C63 is bottom left next to output 0.1uF film

 

[Rob Flinn]

Thanks ToM

That clears up all the problems with the 9K (I think).

I still can`t seem to find C63 on the diagram/schematic though. The diagram I have is rev 1.0 is that the latest one /

 

[SSLtech]

yeah... it never made it past rev 1.0... I got busy!

..and I never made a parts list... and I never corrected the issue with the TL051/TL052 mixup... of course it's an 052! :green:

...It's a miracle that the project ever made it that far! :wink:

But Tommy, tommy, tommy... those red boards look "dee-lish"!!!

-I don't suppose I could talk you into selling me a couple?

Oh and by the way... I got a coupla transformer output driver boards that will kick your boards a$$es in a straight fight!!! :green: :green: :green:

Well, these are very simple, suprising and extremely effective...I'm sure they'd give yours a fight to the end :green: lol

I do have a little secret weapon driver circuit which I like to use (you may remember it from the Clarec rack I put together a while ago...quite a while actually) but I'm saving that for an upcoming project.

 

[tommytones]

And....C63 is located to the bottom left, next to the output connections to the left of IC24 & R84


BTW Keith, I only made a few boards for myself but I might do another small run as some colleagues have been bugging me to put some together for them.

If your talking about on the PCB I`ve seen this, I can`t seem to find it on the diagram. which is why I was wondering on the value !

 

[Svart]

i'll be happy to bug you for some of those 9k boards tommy... :green:

 

[AudioJunkie]

I would also be interested in a pair, if you have some made up. I hate the thought of having to make my own boards. All those chemicals and stuff. Plus i hardly have the room in my apartment or kitchen. ;-)

[tommytones]

I'd be glad to run a batch if there's enough interest but I wouldn't want to get in the way of the boards that Gustav is selling.

 

[AudioJunkie]

Oh yeah. You're right. I wasn't even thinking about Gustav's boards. Forgot he was making the 9K.
