resistors

[Guest]

hi guys, Can any of you kind people tell me the wattage and what type of resistor i should use to replace the 470k and the 1meg resistors on the 6aua tubes of my m102a amp please?I forgot to ask geo these values when i placed my last post about the trouble with the chorus/vibrato. thanks, john

Re: resistors



1/2 watt. Carbon resistors are fine. If you want to choose a higher quality that's OK.</p>

"brilliant" thanks for that george. I hope this is gonna solve the prob cos i m a total novice at all of this . john

Re: resistors

geo,are there 3 resistors in total to change 1 470k and 2 1meg and can i use a 5% tol instead of 10%, cos most of resistors i can find in the uk are 5%. thanks

Re: resistors



Absolutely. Even better!</p>

Re: resistors

geo, ,just replaced them resistors. the organ sound is back to where it was," job done". thanks george for your help , john.

Re: resistors



Okay, appollyloggies for being so thick, but Im gonna try this chorous (on M100) fix also.</p>

</p>

To make sure:</p>

</p>

R-9 resistor off pin 5 is 470 K ohm (whats highest resistance I can go here?)
</p>

</p>

R-10 pin 6 of V1 is 1 M ohm (any chance to put a 1.8 mega ohm- brown,grey,green,silver = colour code - here instead?)</p>

</p>

</p>

I havent been to the amp yet, so if anyone can post picture of exact resistor positions, that be super!</p>

</p>

Re: resistors



If you can find the m100 service manual it should have a parts layout diagram for your particular amp, as well as a parts list which corresponds to the part names (the layout only mentions component names, ie R104, C105 etc, where as the parts list tells you the component values).</P>

What is the purpose of the mod you are attempting? (adding higher resistance values?)</P>

Nuffink mind-bending.</P>


Just laziness - the store to get resistors from is a whiles away and its all uphill (on bike). I happen to have a 1.8M resistor.</P>
