My guess is that they're subscribing to threads the lazy way.

Either that or a very patient bot building up post count before spamming.

My guess is that he/she is racking up the 50 posts to use the sales forum....

 

Cheers,

I'm not too into the DIY... is there someplace where I could get it made for me?

 

thanks!

I'm itching to do some more mods on my Crack but there isn't a whole lot left. I already have the speedball upgrade as well as Solen 100uF film output caps and a stepped attenuator, along with plenty of tubes. I could probably experiment with bypassing some caps - is there any noticeable benefit from it? Maybe I'm just at the end of the road.

Just finished up fitting a Triad choke and swapping out the last electrolytic capacitor in the power supply for a jfx  premium film. Also trying out some K75 100uf PIO capacitors temporarily clipped in with some fly leads. :regular_smile :

Wow, you aren't messing around. Do film caps for the power supply make a noticeable difference? I have one of them bypassed by a 10uF film cap but that's as far as I've gone so far.

have you noticed any difference in sound with the output caps or attenuator?  I would think the attenuator would just be cosmetic.  but who am I to say.  love to hear your input.

While there could be some bias since I can't do a side-by side (and I like to think my money wasn't wasted), I think they both have some subtle effect. The caps cleaned up the sound and increased the bass response a bit. As for the attenuator, I was having a slight channel imbalance at very low levels which is gone. It also seems like there might a bit more clarity/transparency but I could just be imagining things.

I'll have to look into this. if the sound can be improved by simply changing some caps, I'm all in. A nicer volume pot would be sweet as well. could you post up a pic maybe?
