Re: BA BA2 BA4 BAD Dual99v Build Thread

Ha, so that pesky 51R at the output was measuring like 6k or thereabouts. Strange, replaced it and now I have full output! Thanks Joe. I just have one final question, the circuit does seem to have a bit bit of distortion, at least compared to my other BA's- although my other BA's have jlm1.4 and cin...

With impedance fully clockwise I measure 1.2k across RL Am getting 25.3v at Op amp +Out My output transformer seems to read: 53.7ohms between +1 and +2 38.2ohms between +1 and +3 16.9ohms between +2 and +3 23.1ohms between -1 and -2 7.8 ohms between -1 and -3 16.9ohms between -2 and -3 Maybe this ou...

Re: BA BA2 BA4 BAD Dual99v Build Thread

Thanks for your help Joe 1) 21.3 ohms between pins 2 and 3 of xlr input 2) RL = 10k resistor and 100k pot 3) Ratio is set low or middle position of the pins 4) Not a huge amount of hiss, but at about the last 20% of the gain knob's maximum hiss starts and does increase until the gain is maxed. The d...

Re: BA BA2 BA4 BAD Dual99v Build Thread

So can anyone shed some light on my low output distorted BA circuit? My other channels are working fine except for one and I have tried everything. This circuit in question is an OEP/99v/1.1.1 combination. Circuit was working fine before, but suddenly now I have this medium range output, - well I me...

Re: Finally putting my BAs into a rack case

Why do so many people skip the variable impedance????? Its your pre, but I would definitely include it if you are planning now to drill the front panel. Whats the cost/trouble to include one more pot and one resister. With the OEP input xformer I will accept the variable pot is not imediately inspri...

VU Buffer and LED -Please help me understand

Hi I have a project and I want to use the JLM Sew meters, buffer kit and blue led kit. My power transformer has a secondary output of 6.3vac at 2 amps. I realise the vu buffer wants 9-30vdc and the blue led wants 12vdc. Is there a way to provide juice for the Meter and Leds from the transformer? Do ...

Re: MAC - Micro Auto Compressor

Chrisp and Holger - thanks to both of you for your encouragement and advice. You guys demonstrate that DIY is a kind and welcoming environment and I wonder how life would be if such socio-ethos were adopted in the outside world :) Guess I will give the MAC a go. My real wish is to warm up the signal...

Re: MAC - Micro Auto Compressor

Given the excitement of a new kit coming out, I am surprised there aren't millions of postings about the MAC. I am eager to build this one but like the timid little baby that I am, I still hoping to let others be the guinea pigs first and then offer their advice and feedback before I plough into som...

Re: Micro Auto Compressor

Awesome Holger - thanks!

For the point of interest, could you tell us your signal chain so I have something to reference this to? Also interested in the op amps used for the Dingo like Blake suggests.

Thanks once again

Re: Micro Auto Compressor

So has anyone got a MAC up and running yet?

Wanna share your thoughts on the sound? I wait with baited breath.

Joe - earlier in this thread there was a suggestion that maybe a BA could also interface with a MAC -a la Manley vari style - and avoid the need for a separate dingo.

Is that idea still possible or is it only for BADs?

They look sweet.

How far off are the MAC kits?

Indulge my fantasy....... 2 unit rack case which allows stereo BA and stereo MAC into the one case - like a stereo channel strip :D

Hi Joe Are you at all considering making/selling 1unit rack cases for the MAC? I have this horrible feeling that with 500 series being all the recording gear fashion at the moment, those of us in 19inch rack land will be left behind. :cry: Other wise, anyone out there want to make and sell me a 1uni...
