Fastron Inductor Group Buy for JG Filter Buffer

[Jogi]

Hi Fran,

no problem regarding the parts, but the inductors seem to be difficult to get, so that would be nice getting them from you.
And thank you for all your effort

Hi Fran, if I cannot make it with waiting list (already in) please count me in just for inductors. Thanks

Is there a BOM for the buffer?Maybe I´ll get the parts myself instead.

Ok,remove me from the reserve list.

Sorry guys,

This is the first time all week I've been able to get on here. I've updated the reserve list + requests for the inductors...

I don't know if EUVL has an answer from Fastron on this. Mouser shows an expected shipping date of 28/11 - perhaps the ones to EUVL are the same production run.

I asked in the buffer GB thread not long ago. This was from WK on the 19th Nov:

The inductors will be in my hands in next week or the week after.

Inductors are now on the way to me from gogowatch. All going well, I will match these over Christmas and have them ready to ship in the new year.

Hi all,

Just wanted to give an update. I finished measuring the inductors tonight and will start matching tomorrow. Should be no problem getting the matches needed. There were a few outliers - I had a few at 10mh,more at 13mh and 2 at 16mh. All the rest fall from 17.7 to 18.8mh.

If anyone is buying their own in the future, make sure you buy more to allow for this (even though they come from 5% stock....

You can adjust the resistor value after the inductor to allow for these variations.
Important is that the frequency of the LR filter is as designed.

Matching almost complete:

Good job! Thank you for your trouble!

hi Fran
Can you tell me when parts and inductors will be delivered.
Thanks
Tome

 

[woodturner-fran]

Hi tome + all,


Apologies for the delays, I know this GB has dragged on. I am waiting for the 18.9k resistors which Patrick and wk have sent. Other than that, the kits are ready to go. I hope the resistors will arrive in the next few days, adding them to the kits and getting them out will be very quickly after that.

I'm as anxious as the rest of you to get them finished!

Hi Fran, don't worry, be happy. "GB -runners"are heroes!

 

[hochopeper]

Hi Fran,

Consdering that the vast majority of the time has been spent waiting for Fastron and then an unexpected mix up in the BOM I hardly think you (or anyone) has anything to be apologise for

Thanks for your efforts!

[woodturner-fran]

You guys are kind - and patient!

Truth is I'd like to get the gb off my desk so to speak. So I won't be delaying! I have some speaker building, a new shigaclone and the output stage along with a repair job for a friend in the queue!
