mine is a dual-tracking jung 2000 super regulator with improved (crosses fingers) noise reduction and boosted current output for future op-amp and dual-supply projects.

Default Control unit

Being bored of designing large boards with all the required analog discrete circuitry to control and supervise the amp functions (see the PGP auxilliary circuitry), I have decided to build a fully digital control unit around the latest YAP 2.1 power amp. An Atmega 324P MCU will control and supervise the power up/down sequencing, temperature, output offset, etc... Status is displayed on a LCD graphic 240x60 display (Toshiba T6963C controller).

Hardware (very simple) & software (interrupt driven, not so simple, but it's my specialty ) design is completed, now looking after an AVR Dragon and a STK500 to start development...

Upgrading of current amplifier (bigger PSU, making it bridgeable etc), then ty some Full Range Transmission Lines (FRTLs for short), find a new stylus for my record player, make a pre-amp for it aswell.

Then blow something up.

Speakers - prolly a fonken of some sort.

But I do fancy a Pass Labs amp of some sort...

Is there an end to this once the bug has taken hold?

PASS F5 & B1 looking for a good Pre design and then decide on Phonoclone 3 - PS caps and heatsinks proving difficult to source easily in UK.
Shigaclone
O/Bs

Repairs to do:
rebuild Yamamura prototype current amp from early 1990s
realign Perreaux 2150b - 2nd system.

clear up the garage/workshop!

I voted for other, but I guess I could have voted amp or speakers. My next project will probably be a pair of active full range speakers.

I have a couple of other projects on the go at the moment, including a Class A MOSFET based headphone amp, and some 3 Way floor standers which I need to get done. Once I get these finished, I can get started.

Chris.

An active 3-way speaker with current-source/transconductance configured LM3886/4780 for each driver.

Taking forever at my slow pace.
