Ferrites

Such as used in induction heaters and Switch Mode Power Supplies

768T188 Ferroxcube/Philips 0.5" OD x 0.28" ID x 0.19" thick Toroid 3C8 material with 3 sets of windings (very few turns and so easily removed to use the cores) for on-board inverters for vacuum-fluorescent 7-segment tube type early 1970's calculators. (32 available) - $0.40 each

Solid ferrite block 4" X 2" X 1" Has two corners mildly chipped Unknown ferrite material type (only 1 available). $5.00

Toroids, Arnold magnetics # 6T5233-D2-A4 black Square Orthonol material.1.55" OD x 0.9" ID x 0.45" thick. AL=127nh*T2; ui=90; 50 grams weight each. (6 available). $3 each

Prewound 4229 3B7 Philips Pot cores A250 set with two 240 uh windings (or in series 960uh) both about #18 AWG wire with PCB mounting and shielding can (4 available). $4 each

EC52 Ferrite E core. Total core pair size is about 2" x 2" x 0.55". Each set includes a pair of cores, a bobbin, U-bolt but no base plate. 2 halves with no gap, 6 halves with 0.09" gaps. So you can make 1 ungapped set and 3 with 0.18" gaps, or 2 sets with 0.09" gaps (A105) and 2 sets with 0.18" gaps (A65). Will be of Philips 3C80, 3C81 or 3C85 materials (all very similar). Also included are a total of 3 spare bobbins in case you make any winding errors if you buy all sets. (4 sets) Each set $5

EC70 Ferrite E core. Total core pair size is about 2.75" x 2.75" x 0.65". Each set includes a pair of cores, a bobbin, U-bolt, and a metal base plate. Four of the core halves are ungapped and four have 0.19" gaps. These could either be paired to make 4 sets with 0.19" gaps (for about A90) or to make 2 ungapped sets and 2 sets with a 0.38" gap (for about A55). Will be of Philips 3C80, 3C81 or 3C85 materials (all very similar) Also included are a total of 3 spare bobbins in case you make any winding errors if you buy all sets (4 sets). Each set $10



Power and audio transformers

Transformers are preferably for sale in the Toronto, Canada area for pick-up, because of the cost of shipping heavy items such as these, but if you are willing to pay for the shipping I will send these anywhere.)

Electrical Transformers all 115VAC primaries except audio transformers.

50 Amp to 5 Amp (50-400Hz) CURRENT Transformer The Simplex Co., Inc. 2 3/4"x 2 3/4" x 1 3/8" potted in a hv rubbery compound - (3 available) - $15 each or all 3 for $30

Microtran T1104, telephone coupling transformers 600 : 600 Ohm, 300-3500Hz %0.5dB, 0.5% distortion max. 3/4" x 7/16" x 9/32" (5 available) - $1.50 each

Hammond 166L5 5 Volts @ 2A 10VA $3

Signal Transformer DST-6-16, 8 VAC + 8 VAC; 20 VA pcb mount (can be wired for 16 VAC @ 1.25A or 8 VAC @ 2.5A, 120 or 240 VAC input) - $5

Signal Transformer DST-4-20, 10VAC + 10 VAC; 6 VA pcb mount (can be wired for 20 VAC @ 0.3A or 10 VAC @ 0.6A, 120 or 240 VAC input) - $2

11 VAC 3VA (ie. 250ma). separate bobbin sections for primary and seconday (4 6 available) - $1 each

12.6VAC @ 3VA (4 available) - $1 each

USED Radioshack 17 VAC + 17VAC @ 20VA - 120/240 VAC input ie. 34 VCT @ 0.6A or 17VAC @ 1.2A - $4


MINIMUM ORDER IS $20.00, PLUS SHIPPING COSTS (unless you are picking this up in person). All prices are in Canadian dollars.

Shipping is extra, but I can confirm shipping from Toronto, Canada and let you know the options and costs once I know where you are located.
