cmk 0 Report post Posted January 28, 2004 Excellent piece of work. It would be better if you have the option of more than one input. Are you going to sell this commercially? Having multiple inputs means adding a selector switch into the signal path and extra solder joints. I wasn't willing to sacrifice sonics for this as not everyone would need such a feature. BTW, how much did the BB cost you in terms of parts alone? Is it for sale? Share this post Link to post Share on other sites

DIYerStraits 0 Report post Posted January 29, 2004 (edited) A good desing that but ca nbe improved further if you don't mind me saying. One good tweak that you can try is to use 2 12V sealed lead acid batteries instead of the transformer type power supply. You will lose a bit of head room but they would be near-noiseless. With the consumption so low, you'll probably have to recharge them every 3 months or more on continous running. I designed an MC step up phonostage with a 9V batery and it was clean.

With the consumption so low, you'll probably have to recharge them every 3 months or more on continous running. I designed an MC step up phonostage with a 9V batery and it was clean. I've thought of that but opamps have high enough PSRR to behave very well on a well regulated linear power supply. ie. Noiseless.. Secondly, I wanted +/- 15v on the power supply. Also, I can at anytime change the power supply to SLA batteries instead since I opted for the modular approach. Speed is also another factor that I considered since I needed a fast sounding amp. No point going SS if the amp is going to be slow sounding. Batteries alone are not fast enough for me. =) Share this post Link to post Share on other sites
Rameish 0 Report post Posted February 1, 2004 I regret to inform everyone that is interested that the BB amp in now in the hands of a caring new owner. Firefox may be working on a all-out no holds barred MkIII version. Just to give you an indication he's thinking of putting all the money from the MkII sale into parts for the MkIII. Frankly I don't know what better parts he'll be using since the mkII alrady has things like hoveland music caps, nobel pot, Hammond cases, Neutrick combo jacks , Telema tansformer and other premium stuff. I suspect its gonna be a dual mono design - yup 2 transformers - one for each channel. Will it sound different? Will it be the end all for upgradtis fever? We'll see in future editions of Mad Mod World - stay tuned. Share this post Link to post Share on other sites
