Altec DIY N501-8A at 500 hZ.

Thanks to all the members(Altec Best, GM, Zilch, DNV47, Alex d15z6, Earl K, etc.) for the help that I received through my continous inquiries here for the last few weeks! Greatly appreciated!

So far, the 500 Hz XO rules as I had been using it for several weeks now, but I need to find the correct setting of the pots for the 1201 and will report back. Breadboard the XO with polyprop caps but decided to use oil caps for the final assembly since the synergy of my SET amps to oil caps sounds great to me.

What are you running with these?

Your Welcome ! Your using these in a M19 clone correct ?

Altec Best, Zilch,

Yes, I am using this with a so and so Altec 19 clone. System is 416-8B, 802D, 612C cabs, and switchable 811/511 horns using tip of the horn/baffle mount of the LF driver acoustical alignment( about 2 1/2 " from edge of the top of the cabinet) from Altec Lansing Application Notes AN-9.

Thanks again.

Abe

I'm out of the loop on 802D, other than having loaded one of indeterminant provenance with an aftermarket Radian diaphram and not getting a good result. M19 wants 802-8G or 902, in my limited experience....

Hi Zilch,

I will try the 902 or the 802-8G when funds permit. Happy Thanksgiving!

Abe

Hi Abe.

Can you point me at a source for that application note?
Thanks
Les

Hi Les,

I cannot find the link for it but I have a pdf copy that I can email to you.
Happy thanksgiving!

Happy thanksgiving all!


Abe

Hey Abe, Let me give a little heads-up you should only post email addresses in PM's posting them on the board can cause you problems quickly !!!

These forums are crawling with Bot spiders ! And if it happens to be picked up by some unscrupulous individuals,companies,etc.. Could give you Headaches for a longtime to come.:coffeedrinker: Best Wishes & Happy Thanksgiving !!!

PS. I would Edit it soon and just send in a PM = private message. :2thumbsup:


Regards ~ AB

Thanks Altec Best,

Done!

Nice work Abe - sorry just see pictures .I am joining to all thanks to Zilch - information in his posts are absolutely incredible. will try his findings with different capacitance in XO also.I am also thanks to all other members - i am always have a feeling that i am talking to the real gentleman and feel yourself in right company. It is amazing feeling - sorry for my off topic emotions ).
Regards,
Alex

Thanks Alex!

If your XO is still in a breadboard, I will highly recommend the motor run oil caps. Use it for at least 10 hours and compare to polyprop (especially the midrange and the clarity of the top end) and see if you like it.
