My little project is almost finished.

[Dmoney]

SO this has been a long time coming.
It's CLOSE to being 'finished', by which I mean it's close to a point where it might create a noise, but it has a few things to be added yet. Namely the presence and resonance controls, and there is one resistor that I need to source.

I was restricted a bit by the some of the chassis features. I don't really have a drill tough enough to deal with a steel chassis like this, so a lot of stuff is mounted in the original fittings from the Laney AOR.

Some of the preamp boards could be laid out better. This is the first time I've used turrets for a build too, but every time I build something I learn from my mistakes, so I'm getting better even though this build isnt as perfect as I'd like.

for example... the last filter cap for the 1st gain stage, ended up being immediately behind the input jack! I'm hoping by that point the HT voltage isn't kicking out too much noise. There is a lot of filtering in the power supply, and the IEC is an in-line filtering type.

I got some DC heaters for V1 & V2, never done that before! also the AC heaters are elevated. The voltages seem ok, I've had the amp on to measure them. Nothing is making weird mechanical noises yet, so that's good!

Right now, It's like a VHT Deliverance fixed in the 'more' gain setting. The power section is however KT77, since I think KT88's would have been a squeeze. It also lacks the circuitry between the PI and the output valve grids that is present in the D120. I'm hoping it sounds reasonable and then I can start re-voicing it a bit.

Good thing about this, is that the preamp can be gutted and stored away, and a new preamp board dropped in if I feel like sticking something else in there.

That is ludicrously, insanely tidy. Impressive sir! Most impressive!

Thank you very much! It could be slightly better, but at the expense of space and few other things. I try to get stuff as neat as I can.

+1 I really envy people with talent for the soldering iron... I'm a disaster soldering anything....
Congrats!

[Philly Q]

I don't know anything about amps of course, but that's a lovely tidy job.  :D

[Telerocker]

I'm a virgin  :) when it comes to chassis, resistors, soldering etc, so I'm always impressed. This looks very neat. Congrats.

[gwEm]

great job!

what about a picture of the top of the chassis, showing off the iron?

[Andrew W]

As someone whose soldering skills are on the heavy handed side I have nothing other than total admiration for those who do it well. That's some lovely work there, I'm very impressed.

I join in with the plaudits. I wouldn't know where to begin - you have my admiration.

Tidy, reminds me a bit of the innards of an early Hiwatt.

Yup, that's a very elegant wiring job there. And do I see your Marshall tonestack module on the control panel?

It is indeed! Doing that means running less wires between the pots and the board. It also save space on the preamp board. As you can probably guess, the more stuff I try to squeeze onto their, the more spread out everything will be, and then the wire runs to the 9 pin sockets would be even longer.

I decided to go back and carry on with it. Got my board with the presence and depth controls done, and then decided to wire it in. Doing that was a bit of a pain. I always struggle getting my head around which way to wire up those controls.

still need to swap one resistor! annoying! The front panel is from JPF Amps.
Looks good for an old Laney AOR series II, right?




And for Gwem

looks like we have just discovered a new diagnosis tool for OCD ;)

I hope it still looks this way once finished and past any troubleshooting/hum reduction issues

I was going to say it looks like the inside of my old Sound City 120 but with less rust round the transformers and not so many leaky filter caps. And a whole lot less dust.

Fewer wires. Not less. Just sayin.

Well I'm not as clean and tidy as that in any other aspect of life! ha. You're also correct about keeping it neat after troubleshooting and such. things do tend to go a little downhill after that process.
