However, Mr. Atarashi rather used a stepped up model, the H-20-7U (rated 20W at 50Hz) because he thought the H-20-7U …2014-05-04 2:27 am. #12. Hi, Between 2009 and 2013 I have self designed and built two SE DC 6AQ5 amps for my own use. Liked them both. Attached is my most recent topology. Most recent amp used half a 6SL7 DCed into a 6AQ5 with conservative Golden Ratio ( 62% ) plate dissipations, and a 5U4GB rectifier tube.

For 1 6K6 and 10k Za, Pa max = 8.5W, so Va-k = 292. For 1 6AQ5 and 10k Za, Pa max = 12W, so Va-k = 346 (note spec Va-k max is 275, which would require a 6k3 Za to center bias) The screen should be ~50-75V lower than the plate. ….

A guitar amp is worse case since the speaker's resonant impedance peak is usually inside the guitar's frequency range, and overdriving a guitar amp is an accepted practice. I have seen 2KV+ peaks on the plates of a guitar amp with a 430 volt B+, when driven well into clipping. Most tubes will eat far more than their published plate voltage rating.Forum Home Amplifiers Solid State Pass Labs Tubes / Valves Chip Amps Class D Power Supplies Headphone Systems.

This is a version of DaGeezer's Little Wing amp that originally used 6BM8 tubes. I drew up this schematic but never got around to building the amp. use rowlandbrazier watson funeral home obituaries I could get almost 5 watts from a pair of 6AK6's for the same heater power on about 200 volts. There is still a breadboard 6AK5 - 6AQ6 driving P-P 6AK6's amp that I did for the HBAC in a box here somewhere. I went off on a tangent using pencil tubes driving 6AK6's trying to make a tube amp that fit inside an electric guitar.With this power source it is now possible to put a 2 to 5 watt tube amp inside a guitar body.

The transformer is a 100 Va isolation transformer. The output tubes are UL84 / 45B5's and the amp makes about 25 watts of power. fylm sks mqadyturk es paylasim twitterla punetona marlene In my amp, I used a 12AX7 voltage amp coupled to a 6FQ7 differential pair, but I needed that much open loop gain because I applied 18 dB global feedback. Another idea you might consider, but at considerably less output power, is to configure the output stage for triode PP AB1 mode. A 5K OPT would work fine in that scenario. +26 sks kamyra mbashrh If you need to change the 6J1, the American equivalent of the 6J1 is the 6AK5 or 6J1P-EV. 6AK5 variants include 6AK5W, 5654, and Western Electric 402A.
