Deacy Amp (?)

[zbt]

ha ha ha 

just looting around from old junk radio, suddenly a weird feeling become scavenger

probably affected by GAS in component level

That brown has vibrant color, Nice color Nemo
hhhhhhh that fine gold, green muse goblin?
look at this shiny OC44, this BC149 Brian May used it, 
no no no Jimi used BC108, well  2N5133 is the origin,
The Vibe of C828.  Our beloved uA741 famous YJM308, wait 308 thats RAT.
The JRC4558 must be the holy grail

so many old junk
make me wonder how can we use the IF transformer, also so many old tape, the preamp head?
that magnectic head could be use as pickup?
etc... etc...

Okay, for deacy... I think the lo fi is good for guitar.

For me is nostalgia

Old, rusty audio transformers --> Fasel mojo!!

Bought this off Fleabay a long time ago. Would some measurements be useful?

Nice find! I am sure this would make a great deacy style amp. To measure is to know, I for one am curious what transformers are in there.

Naaa... just plug a Rangemaster, TS or EQ and squeeze those Matsushitas!

I ran .OP simulations of the amp stage, just for fun.

Resistors values are driver and output transformers wire resistance.
Since the original have mismatched power transistors I ran two simulations keeping the ratio hfe1/hfe2 far below from unity, 0.4 in this case.
Note power dissipation, collector and speaker currents.





No transistors were overheated during the making of this simulation!
