Real-time playback of songs with predefined lyrics using a MIDI keyboard is.

And R102 was going to be strapped with a cap, but decided there are enough tone shaping caps after the 12AX7s.PS: here's a pic of the amp before I started the rebuild:Here's where I'm at after some fine tuning of the tone components.Ĭoverdell ESA at TD Ameritrade If you're looking for a way to lay aside some money for a young family member or other student, the. I changed the P1 volume control to a 500K pot and eliminated R102 250K.R106 was 220K. I was getting some high frequency noise coming though when P2 was turned in the direction of R106, it disappeared once the P2 wiper moved to about 150K, so I upped R106 to the next highest value I had on hand above 370K, which was 470K (this eliminated the noise issues).I bumped R109 to 180K to make the bass side of the tone control drop later in the knob travel.At this point, the tone control functions nicely and both ends of the tone control sweep are distinct bass and treble positions. Between about 10 o'clock and 2 o'clock, there isn't much variance in tone, but that sometimes happens with single knob tone controls I suppose.With tone 12 noon, as I turn up the volume, I get clean up to 2 o'clock, and overdrive from there on (with o-scope, I can see the signal clipping en route to the grid of the EL84, so its the 12AX7s being overdriven.BTW, original goals are close: It is loud! (a lot louder than previous versions I'd tried) and it sounds really good!Here's the latest with the above mentioned tweaks.Like I mentioned before, the EF86 stage is all Merlin, the EL84 and power supply are fairly standard with some influence from past EL84 related posts here as well as some Merlin & Aiken.The only thing I dreamt up was the treble/bass arrangement mixed together. (the bass arrangement is ampeg's 'ultra-low'). If that looks too adventurous, running a simple voltage divider out of the 12AX7 into the EL84 would work great, I'm sure.The neon oscillator isn't anything new.
