F5 Turbo Circuit Boards

[GentryBa]

hi!

I'm interested in building 2 F5 turbo stereo amplifiers, so I would take the PCB's, too!

OK fellas, time for an update.

Boards are pretty much ready to go for manufacture.
CeeVee is looking over the amp board at the moment and has suggested an improvement in component position which I have carried out.
I will ask CeeVee to look over the PSU board as well.

Before I send the gerbers to the fab house I am waiting for a PM reply from Nelson to confirm that he has no objections.

I will confirm as soon as I have received his response.

Do a small run first to beta the boards. Don't want a big production run with an error that nobody noticed or anticipated...

 

[UKToecutter]

6L6,

Yes I've been thinking about that, perhaps 5 sets (10 boards) to prove the layouts.
Those first 5 sets would obviously be more expensive.
Either way I need to wait for Papa to give the OK first.

Interested in boards

I would be interested in 4 amp boards and 2 psu boards.

I would be interested in 4 amp boards and 2 psu boards.

Added to the list

Add 4 amp boards and 2 psu boards for me too.
And thanks for doing this!

Are you guys doing balanced builds with the 4 boards or 2 amps?

 

[Horio]

I'm planning to do balanced. Do you mind putting me down for (4) boards and (2) power supplies?

 

[chalkandtalk]

Please would put me down for 4 amp boards and 2 PSU boards.

2 amplifiers for bi-amping.........

 

[ra7]

Yes. I'm budgeting for two builds.. or at least extra boards if I mess up the first build

Hi, I am in for 4 amp boards, thank you!

 

[palmito]

Yes. I'm budgeting for two builds.. or at least extra boards if I mess up the first build

Me too...

 

[UKToecutter]

Just checked on the cost for a short run of 10 boards and it's sooooooo expensive.

100 off they come down nicely;

about $11 per amp board and $14 per PSU + postage + PayPal fees.
I know the Blue soldermask is no additional cost but I've no idea if they charge more for Black.

Is there anyone who can do a 'sanity' check on the layouts?

 

[UKToecutter]

Also, It would be good if somebody could sanity check the BOM's for me.

2 amplifiers for bi-amping.........

bi-amping with F5 turbo? we now know the reason for global warming
