Parallel Feed Interstage Transformers

RIT-5 "senior"
5K:5K (1:1)
M6 Lams
channel frame

$125 each

NOTE: add $100 per pair for Permalloy core on either style

Great with 417A/5842 or 5687/7119 as driver.

The RIT-5 "senior" 5K:5K parafeed interstage transformer is for applications requiring high grid swing. They will handle up to 160V rms input for 225V peak output, suitable for driving grids of cathode biased 845, SV 572, etc. Designed to be cap coupled to the plate of the driver tube, with no DC voltage or current on primary or secondary. Available with M6 lams in an "underchassis version" - channel frame and solder terminals for $250 the pair, with Kimber leads for $298 the pair, and you can get either version with Permalloy lams instead of M6 for an additional $100 the pair

NEW RIT-5 "junior"
5K:5K, 1:1 ratio, parafeed only
M4 Lams
solid brass channel frame
similar to the EXO-35/36 in size
Price $99 each Introductory Pricing!

Handles 60V rms maximum input signal, note that this is a *20Hz* rating, not 30Hz like some others use. This will give you a maximum output swing of 85V peak, so this can drive grids of 2A3s, 45s, 300Bs, 50s, etc, anything running with a cathode bias of 85V or less. This unit is specifically optimized for cathode biased tubes. Bandwidth is super flat beyond 100kHz. You want low DCR? How about 55 ohms primary DCR? For comparison, the highly touted NC-20 is over 400 ohms primary DCR.

NEW RIT-5 " junior" NI
Same size and specs as the RIT-5 jr., same awesome 100kHz+ bandwidth, same 60V rms input signal rating. The differences are that the lams are Permalloy and the DCR is a bit higher at 188 ohms in order to optimize the performance of the IT for the nickel laminations.

Air-Gapped SE Output Transformers


16,8,4 ohms, 8 watts, 60 mA

The MagneQuest/Peerless TFA-204 is a conventional airgapped single ended output transformer with a 3K ohm primary and 4,8 and 16 ohm secondaries, rated for 60mA maximum primary DC and 8 watts power handling. Originally designed by Peerless as a replacement for the famous Western Electric A171A transformer used in the WE91 300B amp, the TFA-204 is a great match for SE 2A3 (used in our Afterglow 2A3 kit) and lower power (8 watts or less) 300B applications, as well the best way to modify the ParaS.E.X. to a conventional single-ended topology. The Paramour, Afterglow and B-Glow chassis all have mounting holes that make installation of the TFA-204 a 20 minute procedure. The MagneQuest TFA-204 uses modern insulating materials which take the sweet sonics even beyond those of the original. It would be very difficult to find a transformer with a sweeter midrange. The magnetic design is virtually identical to the larger DS-025 and RS-330 models. Donít let the competitive pricing of these beauties let you think they are "entry level" or "experimenter grade" transformers. These transformers are made with the best materials and lovingly stacked by hand by the premier transformer manufacturer in the universe, Mike LaFevre.

Peerless Output Transformers

The legend still lives on in Peerless, a no compromise design with the highest reguard to materials, quality, and craftsmanship.

These are the only transformers fit to carry the legendary Peerless name.
