Some already mention elsewhere, but here they are anyway.
Antek Inc. has some nice, inexpensive toroidial power transformers.
For QIX's 400 watt (2 modules of 4 FETs) the AN-6450 is ok, but I will use the AN-8450 in future... just for the extra capacity.
The AN-6450 is a 100volt 600 VA and the AN-8450 is 100v 800VA.
Both have 2 primary windings (120v) and 2 secondaries ( 50 volts each).
The price is $67 and $84 respectively, plus $10 shipping.

======================
Been getting some neat little single-pole, single throw relays with 12vdc coils from Fairradio.com
They have nice BIG button contacts...
Last I knew the were $4. each.
Also from Fairradio, , panel meters .......they have the 1ma, 15vdc (you can scale them to whatever voltage with series resistance) , and 10 ADC ...
They are $9. each.
===========================
For the power supply, ant antenna T/R relay, I've been getting the Magnecraft W199x-12 ... usually from ebay.
Those are DPDT, 12vdc coil, 30amp contacts.
New prices are around $25 each, but I have found them on ebay for as little as $10 each "NOS".
Seems like the 120vac, and 24vac coils are much more readily available, and sometimes cheaper, but, I like 12vdc for all my relays (just personal preference).
==================
Ferrites for the transmitter (SB-1020-43)
Still getting those from www.cwsbytemark.com at $1.50 each.
And they still have the PWM filter cores (CH777060) but the price has gone up to $22.50 each!
If you have the enclosure space, using air-wound (PVC core) coils is in ways better, and MUCH cheaper.
But they do take a LOT of cabinet real-estate!

Heatsinks,
I've been getting those cut to length from an ebay seller...
He has 5 3/8" wide, and 8 1/2" wide stock, and will cut to whatever length you want. and he will cuth them lengthwise as well. Good guy to deal with !!
The price is "ok" about $35 a foot with shipping... but you get the same thing everytime, and he makes the cuts for nothing.
Sure, you can find them cheaper if you look around...
But here is a link to his stuff....

Well, I'll post more some other time... hope that's a help to someone!
