Yeah, I'm amazed the small drill bits are still in it. In the handle storage is the key..

 

[laatsch55]

Deoit-ting slide switces...

 

[laatsch55]

Pots back in..

 

[laatsch55]

Time for jacks..

 

[laatsch55]

Pretty good fit on the fiber washers....

 

[laatsch55]

Tedious...its hard to get a consistent bend of the ground tab when its bent at an angle...

 

[laatsch55]

Camera angle makes it appear the tabs on the right are not the same as the tabs on the left..

 

[laatsch55]

Done, now I can start back together with it..

 

[Skratch]

The original inputs are self shorting so when not in use they are shorted for less hum. the outputs are not shorted

 

[Skratch]

when I did mine I made shorting RCA plugs for the inputs when I changed my input jacks and used them on the unused inputs

 

[laatsch55]

Yrp, at least for the phono jacks.....

Progress....

 

[laatsch55]

RCA's soldered in. Still waiting on the RC 4739's...

That is some nice work there, Lee. What are the P/N's of those jacks (asking for a friend...)

 

[laatsch55]

Switchcraft 3501's...

 

[wattsabundant]

Lee, that is a sizable project replacing all of those RCA jacks with 3501's, but probably worth it. Obviosly you've done a lot of work on the board too. I was at a surplus shop in San Jose in the late 90's and found a stash of the original RCA jacks. I bought a pile of them and only have a few left. It looks like you used the fiber shoulder washers on the 3501's which is the right thing to do. Is there not a better solution to the 4739?

 

[laatsch55]

Don, Joe has said any replacement would require a rework of the circuitry. One of these days I'll do it. I do have some Brown Dog adapters with some 2134's mounted just in case...
I have some new TI 4136's and the Brown Dog 2134's for the 4136 also...time to experiment..

 

[laatsch55]

I bought a sack of the orihinal jacks too......except the side lug is on the other side....a shame too, I bet there's 250-300 in that bag...

Just put em in backwards and drill some holes in the top cover for the expensive interconnect wires to come out...

 

[laatsch55]

I had thought of flipping the board over .

 

[laatsch55]

getting 22.5 volts on the plus side of the power supply and 18.67 on the minus side. At the V+,- at each opamp and at the +,- sides of the rectifier. 1N4004's in the power supply....
