History of this page

July 2009

The new address is

http://sites.google.com/site/aldoandr/

July 2000

At the new address (http://www.geocities.com/aldoandr/transistor.html) the page will be updated more frequently than before. The sites considered important references for the transistor radio are now bold.

Settembre 99, Gennaio 2000, Giugno 2000

Aggiornamenti

Giugno 99

Ho aggiunto la sezione AUCTIONS; le aste sono molto utili per iniziare o far crescere una collezione: per le radio e-Bay e' il massimo. Non era semplice mantenere aggiornati anche i siti dedicati alle radio a valvole e ho deciso di toglierli.

Febbraio 99

Dal momento che la maggior parte dei siti e' in inglese, i pochi commenti ai link sono ora in inglese.

Gennaio 99

Ho aggiunto la sezione TRANSISTOR dove ho riportato i siti che trattano prevalentemente di radio a transistor, cioe' quelli che visito piu' spesso.

Luglio 98

Per chi vuole dare un'occhiata a quello che Internet ci offre sul collezionismo delle radio (sia a valvole che a transistor), ho preparato un elenco di indirizzi. Ho pensato a lungo quale fosse il modo migliore di classificarli: l'ideale sarebbe dividere le valvole dai transistor, i musei dai collezionisti privati, chi vende da chi compra....ma poi ho incontrato siti così completi e complessi che si chiamano fuori da qualunque classificazione. Allora non ho trovato niente di meglio che usare l'ordine alfabetico: ognuno poi, dopo una rapida occhiata, si renderà meglio conto di quelli che fanno al caso suo. All'inizio ho riportato un sito utile per chi cerca schemi elettrici, poi i siti italiani fra i quali ho messo anche quello di Enrico Tedeschi che, pur vivendo a Brighton insieme alla sua invidiabile collezione, ha un nome che tradisce le origini, delle quali certamente non si dimenticherà se vi rivolgerete a lui in italiano per qualche informazione.

Aprile 98

Amare la radio (the English translation is contained in this article)

Amo lo radio perchè non invecchia mai: sarà bello il grammofono a tromba ma sa riprodurre solo e sempre gli stessi brani; se invece prendi una radio di cinquant'anni fa, riproduce esattamente quello che senti su una radio ultramoderna. Dici che é diversa la qualità dell'ascolto? Questo è un dettaglio! Amo la radio perchè nessun sonnifero é più potente della televisione: proprio per questo a volte può essere molto utile, ma a piccole dosi. E passare dall'amore per la radio intesa come ascolto del tuo programma preferito all'amore per l'apparecchio che ti rende possibile questo ascolto, é stato un passo brevissimo. E così amo la radio anche perché é un oggetto misterioso: la guardo ancora con gli occhi del bambino che vorrebbe aprirla per cercarci dentro l'omino che sta parlando. Questo amore é cominciato con i miei primi passi (quando mi sono diretto subito verso la monumentale radio ufficiale della casa premendo contemporaneamente tutti cinque i tasti -fono, OM, OC, OL, MF- e costringendo mio padre a chiamare il tecnico) ed é diventato passione irrefrenabile in occasione del colpo di fulmine: era la primavera del '59 quando un amico di mio fratello si presenta a casa per mostrargli una Sony TR610 appena acquistata. La scintilla scocca immediata. Una radio che funziona senza spina, senza terra e senza antenna: un vero miracolo! Io ero più piccolo di loro e 30.000 lire (di allora) non erano certo alla mia portata. Adesso la pagherei volentieri quella cifra ma credo che non basti più e poi non é così facile trovare chi la vende. Solo adesso mi rendo conto che non sono stato abbastanza attento. Sapevo bene che esisteva il collezionismo delle radio a valvole, alimentato anche dagli splendidi mobili di cui sono dotate, ma pensavo che fosse troppo presto per cominciare a parlare di collezionismo di radio a transistor. Invece Internet mi ha aperto gli occhi: sono passati quarant'anni da quel colpo di fulmine e il collezionismo delle prime radio a transistor é cominciato da un pezzo. Questo é il motivo per cui non posso permettermi di avvicinarmi ai primi esemplari ma se posso cerco di sottrarre all'amaro destino del bidone della spazzatura tutti quegli apparecchi, anche recenti, su cui magari basta un piccolo intervento perchè la voce riappaia. Ridare voce ad una radio abbandonata é per me una grossa soddisfazione anche se mi costa molto tempo (perchè non é il mio mestiere) e se il pezzo non raggiungerà mai un valore di mercato.

Chi vuole contribuire ad arricchire questa lista, può scrivermi all'indirizzo e-mail riportato all'inizio di questa pagina.

Grazie, Aldo Andreani
