  2. So, what do you guys think of my front panel layout? I would like to loose the indicator mark on the knob, but it functions in four positions alternating between the four options on/off for gain (high and low (MC/MM) and rumble filter (on/off). The LEDs are bi color green/red, green is on/MC and red is off/MM. The power LED is always green. Just using the same value resistor for both colors, they seem to be matched somewhat. The LEDs are from Bivar and the circuit uses one common-anode and one common-cathode. Just for Nate, I avoided blue

  6. Hello, everyone. Sharing some phots of my recently built Dynalo mini. I have to thank Kevin, Kerry, and johnwmclean in the first place. My machine is pretty hot compared with others on the forum. The transistor heat sink temperature is 88c with 20mA bias(R14/R29 237ohm), 84C with 17mA bias(R14/R29 220 ohm) The IRM 15-24 power module is 16~18C cooler than the fin. The derating of it starts from 50C and shut down at 70C (ambient temp) This already makes me feel the amp working on the shutdown margin, though the sound is still fine. The forward voltage of D1/D2 LED is 1.794V and the R1/R3(increased to 453 ohm) cross voltage is 1.307V after warmed up which means the constant current 2.8mA. I remember the default constant current is 2.5mA, the Max bias current is 20mA and the normal bias is 15mA? Correct me if I'm wrong. Having no ideas about why my dynalo is hotter than other nearly 25C. Could it just cause by the higher hfe of the PZTA/MMBTA transistors? There are only minimum hfe value shown in the data sheet and no maximum is shown. I'll try 200 ohm and 180 ohm in the next week to see if I can lower the temp to 6xC.

  7. Built ikea furniture. Installed this by myself today. Was a royal pain in the ass. Metal studs and toggle bolts are no fun. Came out looking quite nice though. Finished tile and paint on the place a while back. Thought about doing the kitchen next but thankfully time and money have both run out. The tv mounts go up tomorrow. Everything needs to be done by the end of the month as Julie and the kids need to be able to move in there might need to hire someone to help for the next couple of days.

  10. Gud leftovers over here too. Chorizo-leek-Mikey-bread stuffing supplemented with more chorizo and onions to make hash, with eggs on top. AmEx fraud division called while I was cooking, which made me overcook my eggs. Oh well, still gud.

  15. So I've been looking at a bunch of tube/solid state hybrid dynamic amp schematics, and every one of them is some form of bad, or really bad. (one person/ex company in particular) Low voltage plate, capacitve coupling of a high impedance source into a low impedance, poor balance etc. There had to be a better way. true balanced input. dc coupling. low impedance output. no feedback. proper use of a tube (pure transconducance) etc so I came up with this, work in progress. 4 x 3 inches ubaltobaltubeschem.PDF

  18. Looks nice Michael, and agreed on the socket. Having it machined to recess into the front panel might look better as well, but looks great for a prefab case! Here are a couple of pics of mine so far (the usual not even close to being done ) I took Kevin's suggestion and wired the pass devices off to the heatsink for the GRLV.

  19. There's a fuse near the switch. Nice work @astro! Where did you do your casing? Are those temperatures inside the enclosure? Are there holes underneath?
