or what i use is a little blob of paint :)
Job now done and returned to customer
The customer does not use the amp outside of his home. so ive fitted the tank in a reverb bag and place it behind the amp on the floor. works well there
would of not happened if the person who repaired the handle didnt fill the hole with filler then screwed the handle in making the grip nut fall on to the board, Funny thing is i was also given an...
Please to say that the pic chip provided by blackstar fixed the amp
thanks Nick. Ive just posted a reply to that about 20 mins ago. Looks like the pic chip has gone as it does go 3.2v to 0v only with the pic chip removed with it in it stays at 0v
Had my first and hopefully last vaporizer in.
Customer bought it used and says it has a fault with the reverb
Reverb is working but it has a high pitch whistle/feedback
It seems to be...
Ok further testing i believe the PIC chip has gone. With it removed i get 3.2v - 0v when the jack is inserted/removed with the pic chip in pin 14 remains at 0v
I have already requested the part from...
Tested at junction of c163/164 i have 11.5 volts and same on pin 7 IC16 ( not changing when i remove the jack
pin 23 on pic i have 0.5v .... pins 5-6 on ic16 i have 1.1/1.6v
No sound from the amp whatsoever even when plugged into fx loop
I have checked the fuses and as stated in the OP i have 12.6v+/- and 3.2v
Odd job that is making my hair fall out
Customer repaired the handle himself but let the nut on the inside drop out and rattle about
well as you can guess the nut touched the board...
not sure mark. to be honest im going to leave this one. I just don't get enough time to do the jobs as it is
thanks for the help, without the map i won't waste my time
There was bypass and when you switched over to effect. led came on but no signal at all.
tried to trace the signal but i have to admit. No schematic its hard for me.
thanks i will check that out
thank you... I have searched the internet and checked out all these before i post a request .Hoping that someone might have one, but again none of these are about the model i have
thanks Dmeek . im not sure. not the version above
it says MXR 117 version 2 on it
A bit of a long shot. Got a MXR Flanger 117 with no effect but working bypass
I have the original map but there don't seem to be a 117 version available ?
if anyone can assist i would...
I don't do guitar repairs just stick to amps, But i was asked by the guys in the guitar shop
where my workshop is located
The bass went to a local store and was returned not repaired ( same...
easy way is to replace the board. Ive done a fair few and every time i try and repair the board it never works well
i get the board from marshall uk.
Thank you. But all of these are what i have. The schematics are not on these manuals for the L1 Mk 2 and one is the Links is for L1 but the wrong version
This is the version 2 with 2 psu's with their own amps
I have the service manual but it don't come with the maps
Just a long shot
does anyone have a map for this. or any other Energy powered speaker speaker
Yes G1 I checked that. that's ok. I have pulled the semi conductors out the board from that area, can't find anything
this one is starting to try my patience a bit
It came in for protection mode on one channel. while i was testing about. I found a short across a 26.4k resistor R371
I removed the...
Well in the uk its slightly different we have to keep it for 3 months from ready date then i can legally dispose of. We can charge storage, but have inform when they dropped off.
I don't really...
I quoted the customer a price on a new board and he refused it went back to him . It was working just sometimes took 10 sec to come on and when on no issues
Well the marshall ones i get are Tube amp doctor as there is a TAD sticker on them and they have always called the shuguang
these have failed and the other TAD EL84 i get from my UK supplier have...
Not sure if you lot have been having any problems with the TAD EL84's Forget if its the EL84-STR or EL84-CZ
In the past 6 months ive have had far to many sets of these and had a fair...
i have asked tech support. told no to map and only option is to replace the board .
