Have already procured the transformer:

At present i have this cab on hand... thinking of using it for this build.

Actually i have two identical enclosures... only draw back, it has only one input provision.
am planning for a 4 way source selector... so, need to drill holes accordingly.

Started the build:
Mains filter, Transformer, Pre-amp module fitting done.
Drilling to be done on back panel and also front... waiting for RCA sockets.

Hydrovac actually assembled these quite a few days back and posted elsewhere. I asked him to post the updates here too.

Try to cover this exposed metal with a piece of tape, it carries the Live connection!

 

[hydrovac]

Sure i will,
I generally cover the whole power supply with shield to minimize interference...

Update:

To anyone getting the parts for the peeceebee preamp:

C27/28 can be 63V rated.

Input 1uF can be replaced with 2.2uF for a extra LF extension.

All trimmers can be 5Kohm.

I will add these to the BOM shortly.

Update:

BOM updated with above information.

Thanks.

Can anyone know where can buy this 20K Or 50K Dual LIN Potentiometer for "SIG" ?
Any brand and model suggest ?

Shaan is selling some 50k alps pot. I purchased from him for both volume and signature control pot. They are great.
