由於不懂得怎樣post相片上review 33 請見諒。我在香港得閒可以交流下。這對12.1是友人出讓,應該是後期細牛版。跟機一對GEC KT66 及 Mullard EF37 但 ECC33 & GZ32 就不知牌子,可能是蘇聯膽。現在推3/5A很好力及很準確但高音偏硬，想用全原裝膽開聲是甚麼樣。ECC33 & GZ32是否Mullard最好？

For Gingers

We have been asked to dispose of a house full (and we're not exaggerating - this really is a house full) of vintage audio equipment. The original owners ex-wife has informed us that he was a complete nutter, who kept on buying more and more equipment but who couldn't bear to part with the old stuff.

mega rare GEC/ leak 60 watt amps
these were made by Leak for GEC at the same time they made the tl12.1 amplifiers, as you can see they use the same type of transformers
parallel push pull kt66 giving 60 watts
the outputs are
60v (60 ohm)
80v (107 ohm)
100v (167 ohm)
120v (240 ohm)

these amps have been serviced and are working nicely and auction includes 8 original kt66 all tested good. as well as the other valves
just think how they will sound wired up to 4 pairs of ls3/5as in series!!!!!!!!!!!!!!!
In late 1945 LEAK put the original "Point One" series power amplifier -- the Type 15 -- was put into production. It was so named as harmonic distortion products had been reduced to "point one percent". It was announced in the technical press and in advertisments such as those seen in Wireless World, December 1945. Key features of the Point One series that allowed distortion products to be so small were: the use of KT66 valves running as triodes in Class A; high-quality output transformer; 26dB feedback over 4 stages; and a special tertiary winding dedicated soley to the feedback circuit, thus maximising the stability.

The success of the Type 15 amplifier opened opportunities for LEAK to supply amplifiers under contract to other companies, such as GEC. These amplifiers were badged "GEC" but built by LEAK using the Type 15 topology to produce a range of variants to suit GEC's requirments. Most of the of the GEC amplifiers probably pre-date the later TL/12 Point One amplifier (of 1948), but it likely that some were also built after the introduction of the TL/12.

Different variations were produced for GEC, using KT66's strapped in various configurations to obtain different power output and distortion characteristics, and with a variety of input/mixing arrangements. Combinations included: push-pull triode and tetrode; push-pull-parallel triode and tetrode -- giving power outputs ranging from 15 to 60 Watts continuous average, and distortion in the range 0.1 to 0.2 percent. For the tetrode connected variant, LEAK often employed gas-regulator valves (such as the S130) to ensure a stable screen-grid supply -- essential for good performance with tetrodes. LEAK also produced the a 30 Watt Point One amplifier, badged as LEAK but identical to the GEC 2430A.

In proper working condition, these amplifiers will still "cut the mustard" against other amplifiers produced much later on. The value in these amplifiers is in the original LEAK circuits and componentry, so it makes great sense to preserve these as much as possible if value is to be maintained in them.
