I am using a steel chassis, guess it won't hurt, no issues with an umbical.
Not sure if you will know because of the different tweaks but how did the k40 cap compare to the mundorf?
I do not have a layout. The chassis I used is steel but it would sag in the middle a little and know that i would be transporting the amp occasionally that is why I added the aluminum support. I went with just ultralinear because that seems to be the type that Kegger preferred and I wanted as clean and least amount of wire as possible.
I am going to take on the Kegger build. I need to buy a 30 volt power supply to measure resistor and led for the bias of the preamp tube. Are these two power supplies appropriate for this. https://www.amazon.com/dp/B0085QLNF...olid=1OJILDYZM489C&psc=0&ref_=lv_ov_lig_dp_it or https://www.amazon.com/dp/B00LG1TGSE/?coliid=I1RYZCACM0RMI&colid=1OJILDYZM489C&psc=0&ref_=lv_ov_lig_dp_it
I would think so, if the rest of your components can take it. It might also allow you to go to the KT-150's and not run them too hard.Happy new year everyone! I've been really busy but have wanted to build the Kegger se kt88 for awhile now and after seeing blueglows youtube videos I'm sold. I enjoy my 5 watt se builds but have a party coming up this spring and need more power so am ready to get started but have a few questions. I'm going to follow the schematic blueglow posted pretty closely but wonder how he got around 450 volts on the kt88 plates using a 360 volt power transformer. Using psud2 I'm getting around 450 when using a 400 volt transformer with 5AR4. I'm thinking either psud2 isn't as accurate as I thought or the impedance of the power transformer must be pretty small? I'm also am trying to think if I should run it closer to 500 volts and run kt120's for a tad more power.
For my variable dc power supply I plugged a dc wall wart into my variac. I ordered 10 hlmp-6000 led's through mouser and all where at about 1.59v drop with 5ma running through them. Could have used any pair. I also ordered my resistors from them. The koa speer is from what i have read the same as the kiwame but cheaper.
IMHO, no, but it sure looks good.
God is in the details.
Transformers are in, all parts are in, let the project begin. Better than Christmas!
Getting parts for an amp build in the mail is the adult equivalent of looking under the tree on Christmas morning.
