The Amp Garage

Yeah thats what i was wondering. Also, i’m not sure how he is visualizing the orientation of the socket in the layout. Looking from outside the chassis it should be

The iec sockets in diylc always mess me up. On your layout are your wires to the iec socket showing the connections of the rear of the socket (inside the amp chassis)?

Ok, that looks a lot better. Thanks very much. With changing speaker impedances and voltages while playing im imagine this line is moving a lot. I know i like my amps tap set at 8ohm into the 8ohm speaker load (3200ohms) better than when i set my amps tap to 4ohm into the same 8ohm speaker load. If ...

Ive been playing around a lot with this load line calculator. But im not sure what I should use for a correct reactive load resistance. I select EL34 pp pentode, for V+ ill enter my plate voltage 480. For Iq, ill enter my bias point 32Ma, but for reactive load Im not sure. Do they want the primary i...

I did notice that, im not educated enough to know if there would be a difference with AB.

Very informative, thanks. Ive been listening to some videos of 2nd and 3rd harmonic distortion examples. The 2nd has a very warm sound alone where the 3rd almost adds like a clear presence to it. Maybe ken fischer was trying to find that balance between the two with his different impedances?

Yes, thats at idle. I feel a bit better now, thanks.

When trying to get the right OT for an amp should we take into account “sag”voltage? I read that term now and then, i’m assuming its the b+ voltage at the plates and screens of the power tubes when the amp is being pushed pretty hard? This post got me thinking maybe my amps OT 3.2k primary impedance...

Hello, does the fx loop work good when coming from the master volume instead of the treble pot into the fx loop then back out to the master volume pot? Ive always wondered.

Does anyone make pretinned ptfe?

I would build it like the schematic first then try ceramics in the silver mica spots later to see if you like them more.

Its all personal preference but i didnt like silver micas in the amp i made, kind of sounded too smooth in a way. I changed them out to ceramic which had a more aggressive top end to my ears. Not that their any better than other caps but i ended up using synergy caps for most coupling and bypass cap...

The switch worked out great, no popping. Definitely feels different when engaged. Id only use it for the downtuned heavier stuff, as i get older that is more rare.

Awesome, thanks!

Was thinking of a tight switch that could be used for extended range guitars. Its just an additional 50/50 filter cap after the rectifier switched in when the ground is completed by a switch. Would it make a terrible pop if engaged?
