Jeff
Curious if it's possible to change the frequency points of a 553?
I love the sound of them and I'd like to customize a couple for specific jobs.
Would it be a matter of R values or something relatively simple or more complex than that?
Thanks

Changing the caps that are in series with the inductors will change the resonate frequency. It is very hard to lower the low band though. I assume you are after altering the mid band? The bandwidth will change since you are only changing the C. I would not go too far from what it is. YMMV.

Jeff,

The site is showing a quantity of zero... is there an ETA for these?

I am still debating on if I am gonna restock. If I do, it will be after I launch the 3 new EQ's that are in the pipeline.

GASP! I was ready to pull the trigger on a pair...

I am right at the tail end of the build pics for the LC25 & LC40. Hope to have those listed at the store over the next few days. The BT50 will be a month or 2 behind. I need to get the parts sorted for those and complete the build guide pictorial.

Mr. Steiger!

I'm following up now that the BT is complete (which looks awesome, btw!!). Will we see the 553F returning?

Yes I am leaning towards it. I have been very preoccupied with DAWtomation as well as the new version of the FC526 comp. As soon as I get some breathing room there I will get the missing bits in for the 553F's. Hard to put a date on it though at this time.

Hey Jeff!  It's been a few months, casually checking in on the 553F.  I've been patiently waiting to get my hands on a pair    I hope Dawtomation is coming along smoothly!

Hey folks, just wanted to give an update that the new Rev B 553F kits are in stock at the CAPI store.

Working on my build and going great so far.

Quick question, re: installing the op amp sockets... it says in the build guide to install from the bottom...

Anyone using Louder Than Liftoff Rogue 5's in their builds?

I'm wondering if there will be enough clearance btwn the components and the PCB (the components are on the bottom (pin) side of the DOA), or would it be safer to install the sockets from the top instead?

Thanks in advance.

EDIT: For anyone interested, I took the chance and soldered the pins as instructed... Rogues Fives fit just fine.

Hey all! New 553f user, long time builder/DIY'er

Curiously, I'm running into a wild problem on my first 553f Rev B build; PR6, the 10 ohm resistor on that (I believe) sits on the positive  keeps frying! I've replaced it, switch opamps to a known working one, and up in flames again! I'm hesitant to keep trying as I don't want to damage anything else, but I'm at a bit of a loss! Diodes+Caps on the PSU rails are fine, Transistors on the followers/DT07 are oriented properly,  I'm at a loss! Any help would be appreciated <3

HAH, turns out the bottom of the voltage follower was too close to the body of the 2503 and shorting to ground. Got both 553f's working now, they sound incredible! Great job Jeff!
