Are the Ford electromechanical voltage regulators (e.g., VR749) so much inferior to the newer Solid State (electronic) voltage regulators? What is a generic solid state unit equivalent to the Ford generics?

This is the one I think:

I've used Zeftronics regulators for years. Wonderful designs and products.

Yeah, I had a Zeftronics unit in my C172 and was very happy with it. Good customer support, too. However, the question really remains...is this $180 unit really that much better than the $25 legacy Ford unit?

If you need it for a certificated aircraft, yes, you're sorta stuck with a $200 regulator, whether Zeftronics, PlanePower, etc..
If Experimental, the VR144-series is the solid-state version and sells for less than $20 at NAPA et al.

The VR166 that bob discusses in "The Aeroeletric Connection" is a great solid state regulator. They can be purchased at any automotive retailer and are around the $20 mark. I purchased mine from www.rockauto.com and they are a shiny chrome. Looks good on the firewall. They are not adjustable but you can ad a diode to the field wire if you need to increase the voltage output of the alternator. Zeftronics has a PMA regulator that is based on this design.

I thought there are potential noise issues here of 'switching'
regulators against 'linear' designs. The switchers have the potential to
cause noise on the audio system, the linear regulators do not induce
noise but are much more expensive.

My experience in my Cessna is that the modern automotive units go into a
voltage runaway if the overvoltage unit trips, or you turn off the
alternator side of the master switch. Bad thing. The only way to recover is
to shut down the engine, thereby stopping alternator power generation.
That's not practical in the air.
