275-0-275 transformer

You can also reduce your B+ with different rectifiers and/or resistors if it's too high, but you can't make it any higher if it's too low.

And I might look for a 40 watt or 50 watt OT for 6L6's or 5881's. It looks like that piece of gear is gone. I prefer PT's with standup mounting rather then thru chassis mounting but have used both. |Battery disposal information The unit is new construction, varnished and enclosed in Bahr's (USA) vertical zinc plated case with full mount flange. @ 201 mA, Specification Sheet for 700 V C.T. For 6V6GT push pull I have used 6950 ohms when PS output rating was 260-0-260 and did like its sound more than when 8000 ohms was used with 300-0-300 and 8500 ohms with 325-0-325. A tiny Hammond PT is adequate for something like a Tweed Princeton/Champ, This one has a tapped HT winding (for a 'lower powered' amp sound option). Physically, parts were designed to look similar to original factory units (where possible). Something went wrong.

Note: Gray wire is actually BROWN on only our Part Number P-T278CX. http://tdsl.duncanamps.com/tubesearch.php. Material used & design specs. This is a new transformer built in the USA to our orignal design. Lead wires are 600V rated and 6"Long minimum. It isn't though more like a question about two transformers. We are converting over to a USA built product on several of our models this past year. |Imprint Others have argued using lower spec PT's to get the b+ back down results in a sweeter sound. @ 86 mA, Specification Sheet for 380 V C.T. Note- the taps on the mains will also serve to adjust the output voltages ~5%.

I have two PT's hanging around from old radios that seem like they would be in the ballpark of ok. One is a 275-0-275, and the other is a 325-0-325.

If you factor in a 10-20% surplus current rating, the PT will run a bit cooler and last longer. +492158 692 95 54 |RSS Feed. My bias resistor which is supposed to be 470 ohms measures out to 460 ohms.

@ 75 mA, Specification Sheet for 500 V C.T.

I look for a generic OT for that wattage.

Great seller with very good positive feedback and over 50 ratings. These are the same great designs we've built since 2007 with the single largest complaint fixed - they are now available in a USA build at just a small increase in price. I just built a Blackface Champ using the Hammond 290AX. Amp circuits were also different but I think stressing tubes with more current produce sweeter distortion.

Designed for drop in replacement of original units. For those customers who are seeing too high a secondary voltage due to higher primary line voltages (roughly 125V input) - use the White & Black wire and tape the gray wire (see schematic). Very happy I could save another amp from the parts pile. I do feel it's a safe thing to say that The Kinks are the greatest rock band of all time. The main thing is you need enough current: 1) on the heater winding to feed the total heater demand (plus a pilot lamp if your lamp is powered from the 6V winding), 450 + 300 + 150 = 900mA.

See More. I think it depents what output transformer impedance you use?

We are converting over to a USA built product on several of our models this past year. I build and repair tube amps and I can get all of my parts from one place Antique Electronic Supply. The latter would certainly end up running a lot hotter b+ than the schematic, but I have heard some argue that it may actually be driving an old amp with modern outlet voltage that makes people love vintage gear so much.

Because the low B+ on the original schematics (~355) wasn't anything like what the amps ran in reality (which was more like the late schematics' ~410). Phone Support were kept as close as possible to the original part to preserve the stock "tone".

In most circuits this can overcome the difference in B+ voltages when using tube or diode rectifiers.

The fit is not perfect but it mounts with a tiny bit of modification to the amp chassis. That gave me a B+ at 336 vdc. @ 535 mA, Specification Sheet for 800 V C.T. http://thesubjectmatter.com/calcptcurrent.html, Low voltage on cathodes of EL84 output tubes.
