With the meter to the left it is already pointing to the right range. 200mV you should be able to read the mV properly on that setting. The Radio Shack meter only goes down to a 2V range. 30mV on that range would be 0.030 if it is capable of reading that range.

I think it is 90% up to the shipper. I have at the worst had damaged tubes in gear I have sent. In one case it was a preamp tube damaged in shipping I offered a $10 refund to pay for a new tube, but the buyer did not accept, he said no problem since I upgraded to next day shipping for him...

I am having a custom Salvation mod done to cover Diezel Einstein channel 1. That one with my SG XTC will cover my dirty sounds pretty good. Now time to raise funds. MASH-oldano $400 - Great shape just bought it before deciding to have a custom module made. I want to sell it before I get too...

R36 was put back to stock value, and R35 was changed from 1.8K to 3.3K, and now I can bias my EL34s perfectly without being right on the end of the adjustment range.

http://thetubestore.com/shuguangel34b.html That is what I would get. Killer tubes, and $28 for a matched pair!!!

For those not too familiar with the Einstein. Channel 1 is used up til about 2:50 in this vid, all three modes are used. http://www.youtube.com/watch?v=z_it6uaDhGI Another good overview of the modes http://www.youtube.com/watch?v=47rXkGXhNjw&feature=relmfu

It is happening. I will hopefully be posting a pic of the faceplate design, and module name. I am just waiting for the thumbs up for posting details, but this module will do clean, crunch, and mega modes making it imo the ultimate module for an RM20.

OK I just heard back from Randall, and they did some searching. The change is to R35 from 1.8K to 3.3K, or 3.6K I will put the original R36 back in, and change that one out tonight. I will report back once I have made that change so that I can pass on the proper information, but looking at...

This is a brand new RM50 head. I just got it on Tuesday. The resistor that I am changing sets the range for the bias adjustment. By going to a lower resistor value it increases the range. That moves the bias point for EL34s away from the very end of the adjustment where the potentiometer...

Not 10K, that lowers the range. I am thinking that 1.5-2K will be perfect. I will post the exact value once I get it figured out.

Just got the instructions for the fix. R36 change from 4.7K to 10K to get the proper range for the bias control.

I think a switch would be great, a high low range on the bias adjustment would allow a lot more accuracy. A Multi turn pot is just as the name implies instead of a 3/4 turn range or so it has usually 10 full revolutions to cover the full range. Complete overkill, but I am not sure if there is...

I just got off the phone with Randall, and it sounds like it is a known problem of a wrong resistor value installed somewhere. I got the schematic, and I am going to get the details about the wrong resistor value. If I end up removing the bias board I will be looing into a multi turn pot to...

I re-read the thread that I read about this problem in http://www.rig-talk.com/forum/viewtopic.php?f=26&t=45659 It sounds like a common problem. I am going to contact Randall, but I am not looking forward to dealing with this. I just got this amp yesterday, it is disapointing to have an out...

I just got my new RM50 head. It sounds killer!!! But I went to try my EL34s in there, and they bias near the end of the bias pot. I can't get them to be stable in the proper range. I have read a few other posts about this, but I have not seen anything about any mods that can correct this...

I currently have George Scholz classic speakers, and I love them. Other great high powered speakers that I have owned are Eminence Lynch super V, Scumback M75-LHDC, G12K-100 are great, but too modern for some people. Jensen blackbird is 100 watts with an alnico magnet, kind of vintage...

Yes Anthony said it is possible. I am just working out the details, then mondy will be sent. I am very excited about this mod since my Einstein was my favorite amp I ever owned, and I almost never used channel 2. I sold the Einstein because I couldn't justify a $2500 amp for what I do. But...

I am thinking BARK / GROWL for clean/crunch and FENRIR / CERBERUS for crunch/mega Fenrir - From Norse mythology the wolf that killed Odin Cerberus - From Greek, and Roman mythology is the 3 headed wolf like beast that gaurds the gate to the underworld

Here is what I am thinking about for names of controlls Since the Einstein is names after Peter Diezel's dog I would get a custom faceplate similar to the Benzin, but the name would be the Benzin Koda (after my dog) crunch mega switch labled bark/growl I am looking for ideas for a name for...
