RESISTORS - A15 MK2: check your colour codes before proceeding!

Hello all
Here is another thread that documents my quest to build a hand-wired (by me) valve amp that works.
Big problem: as detailed in another post, voltage readings on power tubes triple the value they should be.
Had a couple of great suggestions from Nils and Bernd.
Haven't tried Bernd's yet, but Nils mentioned checking the value of the resistors 51 and 52 on the wiring map.
I went through them all. Those two are fine.
But...
7 resistors (R5, R23, R30, R33, R45, R46 and R64) which are supposed to be 220K / 2W, are in fact 270K / 2W. This comes down to a misreading of the colour code on the resistors (not by me!) 220K = Red, red, yellow, gold. These are Red, violet, yellow, gold (=270K). In all fairness, the violet does look quite similar to red, but it isn't, it's violet.

So, if this difference is significant - and I have to work on the assumption that it is - then I will have to replace all seven before proceeding.
The bad news is that one of these (R64) is on the underside of the power board.

I'll wait for some responses as to whether this mistake is a potential cause of my problem or if the difference is immaterial.
But I have to say: I am just a bit pissed off........

Hello Bernd
Sorry mate, I didn't realise you were an employee.
Of course, I am eager for help.
I have learnt a lot by doing the build. You are right about measuring all resistors
before soldering - but in my rush to construct, I didn't do this.
Lesson learnt!
I'm hoping you are right. I will remove one of the resistors and check its resistance.

As you say, there is probably something else I need to identify.

I thought you suggested starting up different threads?
MUst have got that wrong.
I will restrict myself to a single thread about the A15mk2
Is it me or are there very few postings about building this amp?
Perhaps some have been archived.

Ok Bernd
I am grateful for your advice. I think maybe I misinterpreted some of what you said. My apologies for that.
The threads thing:
Hi
would you like to open some other threads about this topic?

First replace the fuse (correct value! and buy a few of them :p), pull out the power tubes switch on and wait what happens.
If the fuse doesn't blow measure all voltages (except the ones of the power tubes)
Measure also the mains voltage (AC! V)when you do the other measurements.

Bernd

That was you wasn't it?


Maybe I misinterpreted what you meant.

Anyway, whatever it takes to get the amp working, I know I can do it - with your useful advice and the advice of others. It is - however - a bit of a challenge long distance.

Doesn't matter, I am certain it will work out.
I have built a beautiful cabinet for the amp, kind of retro style, but don't want to put it inside until I am certain all the wrinkles have been ironed out.
Many thanks again for your help.
