These are answers I need.

Thanks.

Look what the mailman/woman dropped at my casa.

A matched quartet of GM70's (Almost ashamed at how little I paid for them) GM70's are for a SE GM70 amp with MQ parafeed iron.

And the 500R trimpots and 0,22uF caps for the Baby Huey.

A main reason I'm active on this project is the event coming up on the 5th. For me there's nothing like a deadline to get me out in the garage.

A lot left to do:

• MLS measurements - on/off axis at varying output impedances for 3 drivers will make for quite a few measurements
• Figure out how to enclose the mid - I'm thinking open back at the moment
• Design the active crossovers in Soundeasy
• Build the active XOs - point to point likely using FirstWatt B1 type buffers (two JFETs isn't much more work than an opamp)
• Paint

Two weeks left!

edit: applogies to anyone viewing this at less than 1280 screen width... It formats properly with that (two images side by side) but I'm not going to go and redo all the images now!!! I already did twice....

OK Continuing on where Part 1 left off. The next step was to attach the Power Supply wiring. I will continue the numbering from the first blog entry for consistency.

18. 19.

images 18 and 19 show the completed amplifier with +ve -ve and zero volts wires connected. Note also that there is a separate zero volts return from the zobel capacitor to the star ground on the PS board. The red wire is the +ve the blue wire the -ve and the green wire is the zero volts. The return for the speakers is direct from the speaker output jack to the star point on the PS board. So in all there...
