1974 …
Preamp and power Mullard tubes, Partridge transformers …
An horrible Bulgin AC-chassis jack ablation !
Oops, old RS cap (the grey one) -> recap needed !
Components easily accessible and very clean wiring !
On of the screws that maintain the chassis is missing. Diameter is 5mm, an old thread of 0.9mm, hard to find a replacement. Washers are missing, too, so the chassis is badly and loosely fixed.
Hiwatt recapped !
Screws replaced
Power jack replaced
Done !

I’m trying to figure out what tube is the phase converter on my 1978 DR-103.
Thanks
Hi Mark,
I think it is, as previous 4 inputs models, this one :
It is either a 12AT7 (ECC81 : more headroom) or a 12AX7 (ECC83 : more gain)
Hi, thank you for this info. I need to know what capacitors (if I change the whole bunch) I would need. If you can maybe supply me with a bill of materials, if you’ll be so kind.
Regards
Thean
