What happened to your original 25 ohm pots ?????
perhaps they needed cleaning to work properly.
I just replaced the 25 ohm pots on my stock N-800-F crossovers because the originals were non-functional. Unfortunately, I replaced the called for 25 ohm pots with 25K ohm pots. Needles to say, they are also non-functional-just on-off switches.
I have a couple of 16 ohm L-pads but I am unsure how to wire them up in place of the stock pots+20 ohm resistors. Any help appreciated.
I am planning on cloning the crossovers with PIO caps and new inductors soon but was hoping to get the stockers functioning better.
Other advise welcome.

Here is a schematic of a 16 ohm Lpad that might answer your question.

Many L pads aren't L Pads. So the answer depends on which L pads you have. If it only has 3 terminals it may just be a 16 ohm pot.

Both were frozen. I sprayed WD-40 into them and gently worked them back and forth over 4-5 days but could not get them to work. Finally they began to move but the insides were trash.Originally Posted by 604man
Wondering too, but FWIW, I've been using a visually identical pair of these dinky 25 ohm pots to dial in DIY speakers since my first SS amps in '70: Amazon.com: 25 Ohm 3 Watt Rheostat 25 Ohm +-20% Tolerance Wirewound 3-watt Variable Resistor Potentiometer: Toys & Games

Cool! Much better bargain nowadays, back when RadioShack was still around the one I use was only ~ $3.50 a couple of years ago.

Looks nice to me - but - some 2-way Altec crossovers have 2 pots - one for Frequency, one for volume, if I read it right?
A single pot is for shelving a tweeter [horn], two includes one for the mids; combine them in a two-way and you have a constant directivity [CD] tweeter [horn] EQ filter, something that became necessary for max fidelity when recordings began adding more 'musical' HF > ~11 kHz and especially when switching to voltage drive solid state [SS] amps.
