First build is alive.

Post by declan »

Here are some pics of my first amp build, I couldnt believe it when i fired her up on the bulb limiter and things started checking out. Unfortunately I have a cheap DMM which has been giving strange readings at the top end of its scale so i did not dare go any further than check voltages and a few second strum. Some of the B+ voltages are reading high so I intend to sit down with it next week with a decent meter before going any further.

I havent posted many questions here as most of the answers I needed so far were but a search away but I fear that it is now getting to the limits of my competence, so I will ask forgivness now for any stupid questions you guys have to suffer over the next few weeks.

Heres #1

If my bias voltage range is too low is it the 220k resistor across the PT secondaries that needs lowered?????

The cab is being left with a friend next week who does wood burning art... I have no idea yet what i am going to ask him to do..
