    Certain driver specs and maybe speaker designs? Damping factor is defined as the nominal output Z of the speaker divided by the output Z of the amplifier. Screw connections are provided on the PC board. Electra-Print still makes very good transformers, but they are considerably more expensive than when I got them. A few millivolts of bias is not going to be a problem. Just my. HyakuyaOct 25,

    At the time this manual was written, the Tubelab SSE has only been tested as a stand alone single ended amplifier. Power Output Simulations for KTI have used these with good results.

    Tubelab SSE. The SSE (Simple Single Ended) board is used to make a simplified SE amplifier that uses indirectly heated tubes like the 6L6GC, EL34, KT88 and.There are likely other transformers available to builders in other countries that I don't know about.

    More specifically, the Tubelab Simple SE with KT88s vs the Tubelab Simple PP running EL84s. Looking to DIY my first tube amplifier.Powered by SMF 1.

    heavenmanga.online › forum.I have absolutely no hum coming from the amp, just the old guitar amp power transformer is a bit noisy, put some extra rubber under it and now it is a bit more quiet.

    On this basis I think kt88 would be the best tube. However finding decent output transformers at a good price that offer good bass response.Hi Strider, Notice I bypassed how to figure the output Z of the amplifier.

    Tubelab Simple SE with KT88's This is a DIY amp I built a few months back. I was getting into low powered amps and high efficiency speakers.The power output, distortion and damping factor values are also given.

    Tag Archives: KT88 He suggested I build a Single End, class A amplifier and told me to do some research on heavenmanga.online and heavenmanga.onlineI have absolutely no hum coming from the amp, just the old guitar amp power transformer is a bit noisy, put some extra rubber under it and now it is a bit more quiet.

    I read this article(Power amp adapter), I built a Tubelab SSE amp with KT88 tubes and these outputs, CXSEK - 25W, 5K Ohms single ended.Quote from: Thirsty on 31 Octpm.

    Is the ohm Rk (KT88) and ohm Rk (EL34) still believed to be the tube simulations for the popular Tubelab SSE single ended amp.Share This Page Tweet.

    A center tap on this winding is OK, but it will not be used.

    The primary winding should match the line mains voltage available at your location.

    A few things I'd do differently next time but I've learnt so much in the last 6 months.

    This small component acts like a ohm resistor when it is cold initial turn on and gradually reduces to about 2 ohms as it warms up.

    From the schematics of the amp, and from what I got from scanning the interweb, the output impedance of a tube amp is determined by the output transformer.Forum Tubelab kt88

    I followed the BoM which Mark created and got the 10W resistors but I'll most likely follow your advice and swap them out for some 50W items.

    I'd look into the damping factor on both amps, and what that Hawthorne driver needs for damping.

    It looks like the mk2 se board will be released any day now so it should be available again soon.

    Unfortunately, these are way too expensive over here, the big Hammonds are a bit cheaper, so I would recommend using these.

    They sound great to me but it would probably not be worth spending on fancy output transformers if this is the case I have read something earlier about smaller cheaper transformers having faster transient response, if both of these statements are true thenn I might as well by small edcors or hammond units i think.

    That bias point is up the chart because of the lower plate voltage driving the dissipation compared to your amp.Forum Tubelab kt88
