scored a couple of freebies down at the thrift shop,

gonna see what gives,

 

[CJ]

de lam,  after a heat-up

i bet the odds are fifty fifty,

 

[CJ]

hate your job? you should try this,

58 lams, EI-625 , plus two keepers, 13/16" stack, = 0.014"

 

[CJ]

hack masterson at the controls,

 

[CJ]

looking for some copper,

 

[CJ]

must have ran out of Permacel P245 in 5/8"

 

[CJ]

trouble from the git-go,

bi-fi, 

major spliceage,

 

[CJ]

one layer of hand wound bi-fi,

 

[CJ]

somebody went to the stockroom for some 3M# 56 in 7/8"

 

[CJ]

this section looks like major turnage,

hand wound,

about 175 tpi,

 

[CJ]

no breakage so far. means we can get dcr as broken terminal splices prohibited this earlier,
wire stored on 6" empty spool,

time for some microwave junk food then back at it,

I reckon this is as close as you can get to alchemy today.

looks like about 3780 turns in 4 sections into a bi-fi sec with 419 T = 4.5:1 if you series the sec winds

83T bi-fi could be taped for 5.8 ohms twice if you wanted feedback,

12K:600 

 

[CJ]

looks like the same ratios as the 217  ;D

what a coincidence,

I stumbled across a few photos of CJ's workshop the other day. I'm sure he won't mind if I share them:
