Thanks for the tip Tim, I'll keep my eye out for those.
Gonna need to get a tube tester too one day.

Need new ones? I just got 3 quads of these for my Hafler 220's. Great deal on 100v 10kuf caps. I need to buy some new power supply's now, to run those amps in dual mono!:)...

After 4 orders that cost me about $30 in shipping, I finally got everything I needed!:banghead: I either ordered wrong, forgot something or didn't pay attention to temperature spec. Oh...

I ordered caps to do 4 of my older haflers but went off of my original manual that includes the schematic and parts list for the P500. Well it's incorrect! I should have taken it apart 1st and I know...

Gonna order all the electrolytic caps for the driver boards and balance boards today for the P500s. Might as well do all the small electrolytics while I'm in there!:) Going to wait on the power...

I set to bias at 330ma but could and go little higher but I try and keep the fans running at slow speed. The bias is less on the 200's and 220's. 275ma bias is spec for the 220 and I guess it's the...

The later DH200's had the same board too, mine does. Yes, I have more Haflers LOL.:dont-know:

Good idea replacing all the electrolytic's and I've considered it before.
I think that's the plan...

Their not broken at all and I routinely set the bias and dc offset. They still kick hard.:)
I don't really think that I plan to move these out of the house much and I like to work with electronics,...

I'm thinking the same.
I bought the QSC because I have a minor ambition to rent out my gear out and play soundman and that amp is really light compared to the Haflers. I know a few bands I could...

Is it worth it? :dont-know:

I'm so attached to my my poor old Hafler P500's but I just picked up a QSC PL340 to run my 18's and the QSC is so much better sonically than the Hafler. Of course the...
